What you're asking is if you should replace the HAL with a reprogrammed GAL in your 128k Toastrack,
I would say that if you've never encountered the error it causes then you could probably save yourself the trouble. If it is important to you to have one less bug in your Toastrack then by all means go for it...
Do you have the GAL's and a programmer lying around or would you need to buy one? Owning all the necessary equipment already could make the hurdle a bit lower and make deciding easier as well.

but like you say I haven't really noticed an issue.
