Something to that extent is even documented:
"""d = # open, with (g)dbm filename -- no suffix"""
"""As a side-effect, an extension may be added to the filename and more than one file may be created."""

Still, it's super-quirky, it's almost as if the message was "don't use shelve."

Some ways out:
* ValueError if "." in basename(filaneme)  # a hammer
* ValueError if filename.endswith((".db", ".gdbm", ...))  # block only known extensions
* strip extension if it's known that underlying library is going to add it
* patch underlying library to always use filename verbatim
