it also depends if you are performing in ensembles together with historical instruments that can't change their pitch, or on those instruments on their own, for example for organs you can find examples up to A=465 This said I think it's more fun to talk about temperaments than absolute pitch, after all unless you have absolute pitch I don't think you can hear much of a difference between something played at 432 or 440, but going from equal temperament to something else is a lot more noticeable and makes a lot more impact to the music if it's written taking that into account.
