I would be far more sad at the battery life of any Intel Mac anymore! Having been on Apple Silicon for some five years now, I can't imagine going back.
My buddy runs an independent video production company and bought a specced out Mac Pro for $12,000 in 2019. Probably still quite capable and battery life doesn't matter on that.
But I also understand it being deprecated and for Apple it's only gonna simplify platform improvements going forward to drop a second supported architecture. And at any point in computing history, 6 years was a decent lifespan for a machine.
