instead of the compiler storing a code object as the annotations

Would that tuple be significantly smaller than the corresponding
code object, though?
It would only be slightly smaller. The point of doing it would be to
boil out fields that change per-object (e.g. co_name) so that functions
with identical signatures would share the same tuple both in the .pyc
and at runtime. This idea is predicated on Inada-san's assertion that
this is an important memory optimization, that there are large
heavily-annotated projects with lots of functions/methods with identical
signatures where this memory savings is significant.
