Absolutely. There are no excuses for regressions. If the code was
badly written and left itself open to user space "misusing" it, it's
our problem. Especially if the code was badly written to begin with,
and user space worked around our bad code.
We don't then "fix" code and blame user space for doing bad things.
In particular, we don't cop out and say "hey, you didn't follow the
docs" (whether they existed or not) or "you didn't do what we meant
you to do".
The _only_ thing that matters is that something broke.
