In the case that triggered the discussion, the change implemented was not an incompatible change, because the new implementation still met the old specification (which, of course, was underspecified). No, it wasn't, actually. Read the doc strings, which state exactly what the code does.

The doc strings were precise, yes. The documentation (Doc/lib) was underspecified and allowed for both interpretations:

splitext(path) Split the pathname path into a pair (root, ext) such that root + ext == path, and ext is empty or begins with a period and contains at most one period.
