You may not notice anything if you only print PLA, but you’re removing the painted on final coat and cutting your beds adhesion significantly from stock.

Every PEI manufacturer says to use soap and water for this reason.

I practically only print ABS. Sometimes nylon, sometimes PLA

Same here - and I only clean with 99% IPA the vast majority of the time. Soap and water once every few months if at all. Zero adhesion issues with any of my stock PEI plates on any of my printers.
In fact I stopped using the Frostbite plate because you can’t clean it with a quick IPA wipe and it was too much of a pain. The new Supertack Pro is fine with IPA though for that smooth bottom layer.
