Cellist for the last 35 years here. No perfect pitch. My "perfect" note identification is based on timbre: I know what each note sounds like on the instruments I know intimately.
For synthetic tones, I will be off +/- 3 semitones because I will be using an aural memory of the cello a string as a reference, rather than recognizing the frequency like the perfect pitch folks do.
Never occurred to me to practice perfect pitch because, as you said, it is not that useful.
