My working theory:

The change modifies the MAP_ADD instruction and also what the instruction expects to find on the stack.
When *.pyc files are kept, the code generates the old stack layout (TOS=key, TOS1=value), but cpython will assume it's the other way round.

I.e. all *.pyc files created before the change won't work with later cpython versions, and vice versa.

I assume the build bots don't remove *.pyc files.

How large an issue is that?
