From the musicians I've met who have it most have actually highlighted the annoying aspects of it more than the useful aspects, in that they can find it bothersome to hear music they're familiar with played in different keys or offset from standard pitch.

I've never experienced any correlation between pitch sensitivity and improvisation skill in groups of trained musicians.

I play a lot of improv and normally it takes no more than 2 notes playing along to determine the key of the piece and relative pitches are very learnable.

That one has an extra layer to it. Many people with absolute pitch will start drifting as they get older due to physical body changes. I've heard the comment of "now everything seems out of tune and annoying". I'm not sure I'd like to experience that as a trade-off.

Losing some high pitch hearing is bad enough.
