Well, my exploration arose from discovering something in PL/Java's
implementation that surprised me, but it dated from pre-9.0 times,
so seems to have been doing the best that was possible then. Didn't
want to start changing it before understanding why it was that way.

As for bringing it along to the modern API, am I on the right track
with writing a ParserSetupHook that's just a thin wrapper around
parse_variable_parameters ?
