PEP 387 also contains a detailed process for making incompatible
changes, which calls for warnings to appear in at least two releases.

Do you think the process section can be ignored? We should remove it
from the PEP if that's the case.

I don't think it should be ignored and the modules got yanked prematurely. A request can be made to the SC, though, to expedite the removal with only one release raising an exception.
