There's no *requirement* to actually spin

Sure there is: 61.817b1xi (Flight Proficiency) requires a CFI
applicant to receive and log ground and flight training in a number of
specific areas, including spins.

To say that you can satisfy the flight-training requirement for spins
without actually ever spinning is like saying you can satisfy the
flight-training requirement for stalls without actually ever stalling.

That's my point -- the language is ambiguous, and some have taken
advantage of that ambiguity.

"Receive a logbook endorsement from an authorized instructor
indicating that the applicant is competent and possesses instructional
proficiency in stall awareness, spin entry, spins, and spin recovery
procedures after providing the applicant with flight training in those
training areas in an airplane..." is not the same as "The applicant
shall demonstrate instructional proficiency in recovery from a fully
developed (minimum two turn) spin to the right and to the left..."

The CFRs are VERY explicit in other areas (number of takeoffs and
landings to full stop, number of approach, etc), but seem
intentionally ambiguous here.
