IANAL, but I think any manuever required to pass a certificate could

chandelles etc. (required for Commercial) would be OK by 91.303. Can
anyone (CFIs?) confirm or deny this?

Spins are required for the CFI-Airplane rating. Maybe also on the
PP-Glider test? I doubt anybody would consider a spin "necessary for
normal flight".

On the other hand, the airspace around here (New York) is so
chock-a-block full of airways, if practicing stalls or chandelles in an
airway is a FAR violation, I would imagine we've got a lot of violating
going on every day in this neck of the woods.
