Your TOS rom are standard part number. It's simply mask rom, not (homemade) EPROM ;)

So that must mean that most roms I have seen were upgrades.

If it's EPROM with sticker on glass, yes it is.
It's easy and cheap and legal. I have done it on all my STE, even with a switch to change between 1.62 and 2.06.
