Hmm, yes, but that mixes up the object you're automating with the
one that's receiving/handling its events.  I find that somewhat
unpleasant/untrivial.

Every file built by genpy has the following lines towards the start:

# The following 3 lines may need tweaking for the particular server
# Candidates are pythoncom.Missing and pythoncom.Empty
defaultNamedOptArg=pythoncom.Missing
defaultNamedNotOptArg=pythoncom.Missing
defaultUnnamedArg=pythoncom.Missing
