This looks like it has more visibility than necessary. And it seems
incorrect for anyone in the crate to care about MMU version details.
This can probably be just 'mod ver2'. There are a lot of other types /
functions in this series that could have tighter visibility. Could you
go through and see if you can reduce a bunch to private or pub(super)?
