.. however, this is not an argument for adding a *new* interface.

You are still stuck handling the old one, so adding a new interface
without holes doesn't help *anything*. It's just a bad idea.

So we're stuck with the interfaces we have. Don't say "let's fix the
problems by adding new ones". It doesn't work, it doesn't solve
anything, and all it results in is even *more* interfaces to maintain
and find bugs in.

It's also a major pain for testing, since different people will
invariably use different interfaces. So a person running an older
distro will see a bug that the maintainer cannot reproduce, because
they maintainer has in the meantime updated to all the new and
"improved" interfaces.

So "new and improved" is just bad. Fix the existing ones, instead of
saying "oops, that was a bad interface so let's make a new one".
