Why don't custom roms update the radio as well?

[Nobi125]

I don't intend to sound ungrateful or criticize any rom chefs/modders/programmers, I'm only asking this because of my lack of technical knowledge on the issue.

I want GPS and Rev. A badly, but do not feel like waiting till 2013 for Sprint to release an all-in-one update (also getting really tired of reading a rumor about a release and getting let down repeatedly).

I assume there are others like me that have never even flashed a custom rom, let alone flashed multiple roms in a sequence, then installed drivers/dlls, and make other adjustments. It seems like there are a lot of ways that the current method of getting the update can go horribly wrong, due to how complicated it is, for someone without a decent amount of experience doing this sort of thing. Judging by comments I've read, updating radios is pretty risky no matter how skillful you are.

Is an all-in-one solution (similar to what Sprint will theoretically release) even within the realm of possibility for the talented group of modders/programers on this forum? If so, is something like that in the works?
