You're right, it's not. Perhaps you could send a message to the interface
package development list?

Why does this disturb you? Would you feel better if it were called

A gets an additional attribute. Its behavior doesn't change in any other
way. I don't really see what's wrong with that, unless you have a differing
definition of the __provides__ attribute in your code.
Is there a way to avoid this?
Depending on what your definition of "this" is, there almost certainly is.
In the simplest case, you could submit a patch to zope interface.
Doesn't this seem like a bad idea?
