I think if your linter or editor can take note of the pdb idiom, it can also do so for the debug() built-in.

I don’t think that’s a good idea.  pdb is a thing, and that thing is the standard library debugger.  I don’t think ‘pdb’ should be the term we use to describe a generic Python debugger interface.  That to me is one of the advantages of PEP 553; it separates the act of invoking the debugging from the actual debugger so invoked.
