Since -current has a different major number from -5 (because of this
and other changes) introducing these into current would serve no real
purpose and potentially make a mess.

Introducing them just into -5 seems fine though, assuming you intend
the usual __RENAME method.

(Also remember that since PUFFSOP_INIT is a macro you don't have to
change or version it.)

I'd suggest doing the patch to enable puffs_ops_spare[] separately
from the feature patch.
