From what I’ve heard, absolute pitch can be distracting in certain scenarios, like if you are listening to something which does not use A=440 (more common than you might think, just imagine that some instrument in a band is flat, and then everybody else tunes to match that instrument, or consider choral music, which drifts over the course of a song for various reasons). The other problem is that absolute pitch often drifts as you age, so someone with AP in their 40s or 50s might start hearing everything as out of key, because their sense of pitch has drifted.
