Just found the firmware tag (x38), where questions mostly refer to either rom (x78) or custom-rom (x141).
Suggestion:
- remove the firmware from those questions already tagged custom-rom
- merge firmware into rom
- make firmware a synonym to rom
Though there's one more thing to consider: firmware may be ambiguous, as it could as well refer to radio-firmware (x6). How do we deal with ambiguous tags in general, and especially in this case?
