The two errors mean different things: ModuleNotFoundError means literally that the module could not be found at all (i.e. no import hook offered to try to load it)

A plain ImportError then means that the module was located, but attempting to actually load it failed.

find_spec()/find_loader()/find_module() implementations on import plugins shouldn't be raising exceptions for modules they don't offer, and hence shouldn't be needing to raise ModuleNotFoundError directly.
