If it goes bad, does it cause a permanent traction ON
or does it allow the engine to run with nothing
holding it back like being in the competition driving setting?

The typical failure mode sets code(s), illuminates the traction control and ABS lights on the dash and allows normal operation of the car minus ABS and traction control.

Don’t yell at me because I have no idea about how to work on these or for that matter any cars.I have a 98 and have been reading more about this problem. Mine works, but for how long? It seems like there is no way to replace them for a 98.
It looks like they can only be repaired if that is even possible. I would need to find a shop that could get one and install it as well. So, if and when it does crap out what to do about it?
Would I need to throw the engine away and get a new one?
or
Can they cut some wires or hoses or something easy?
Maybe I should get a new one with a warranty that has it's own set of 100 things that will wrong?
Or maybe my moms 62 Buick station wagon with crank up windows?.

How long? Who knows. Cannot be repaired or replaced, unavailable for a long time now. Will not effect engine, don't throw it away. Cutting wires or hoses probably won't fix it either. Mine has not worked since owning it, no problems.

If or when the ECBM goes in my 97, I'll probably go with this.

I am deleting it for the room it leaves not to mention air flow through the radiator must be improved without that big item right behind it. There is this as well. My rear brakes are pretty much inop under normal pedal pressure, this was confirmed while it was on Quick Jacks. Getting rid of the dead EBCM and putting a prop valve will allow a fine tune of how much pressure the rears get.

.....but the EBCM provides pressure through the secondary circuits. If you have no brake pressure at the rear wheels, your problem is most likely else where. Are you unable to perform a manual bleed to the rear wheel?

Power steering cooler, oil cooler, trans cooler, etc. Go look at your car, see the huge unit right behind the fan on the drivers side? I didn't say NO pressure, reduced pressure IMO because the EBCM is cooked. Brakes bled just fine, pedal feel is excellent. With a prop valve I can tune in how much pressure the rear calipers see, how is this a disadvantage?

Ok, so you are building a Auto-X car. Got it.
I never said anything about a disadvantage. I asked questions based on your words "My rear brakes are pretty much inop under normal pedal pressure". That suggests to the reader that you effectively have no rear brakes, which would typically have anything but excellent pedal feel.
In your opinion, you think the EBCM being "cooked" is somehow posing a restriction. Not saying that is not possible...just not plausible.

Because I am a crazy car guy and don't want a broken part in my car that doesn't work. I guess it is a similar reason as to why I spend all sorts of money for upgrades and parts just to make my car go faster, look cooler and sound better, imho.

This is the long boring story about it.
I think that that this generic explanation describes the way any car with ABS works.
If I was able to find the correct unit at a reasonable price
for my 98 I wouldn’t even be able to install it because I have a disability. It sounds like getting water and debris on it may hasten its demise. My car has never been driven in winter weather and maybe only 3 x or so in the rain, stored in my heated garage under a cover, so the engine and engine bay are extremely clean and I keep up with regular maintenance. It’s just a toy that I don’t really need, just for fun. But if it isn’t drivable there goes the fun. I don’t even know if I could find a shop that has the expertise to install it correctly.
It looks like they can be repaired by somebody that knows what they are doing, but that’s not me. I did find a company that sells used rebuilt ECBM units but the cost is outrageous. I would like to have one as a back up because it seems like a common problem.
This is the correct unit;

WTF!!!!!!!!!!!! Really low price.
They do have a really good rating

Based on 4 reviews, WOW
