This means verifying all the users before patch submission, which may be
problematic.
I guess the point I'm trying to make is that if you create a new API you
have the option of converting the obvious cases first, which should
cover the majority of users. Anywhere the behaviour is non-obvious can
be left using the old API, and the out-of-tree users will continue to
work correctly.
