Yes, that's essentially what happens in the current release. Bash sets
the binding for TAB in the vi insertion keymap to `self-insert' when
enabling posix mode and to `complete' when disabling it. There are a
couple of ways to handle the issue you've raised, but it has not surfaced
as a problem before, so it doesn't have a high priority in the work queue
right now.

This just isn't true. TAB is bound to `complete' when you disable posix
mode with `set +o posix'. Since the only binding that gets changed when
enabling or disabling posix mode is the one for TAB, any other characters
you have bound to `complete' retain their bindings.
