An API breakage that gets noticed *is* a crtitical bug.

You can't call something else critical and then say "but it broken API".

Seriously. Why do I even have to mention this?

If you break user workflows, NOTHING ELSE MATTERS.

Even security is secondary to "people don't use the end result,
because it doesn't work for them any more".

Really.

Stop with this idiotic "only API". Breaking user space is just about
the only thing that really matters. The rest is "small matter of
implementation".
