What unpleasant surprise is that going to be? They'll get an error
message telling them there's no inline support. That seems to me to
be more user-friendly than forcing them to type out the language name
and then getting the same error message.
As for the overhead, these queries are not zero-maintenance. I still
think that the usefulness of tab completion here is pretty darn minimal,
since most people are more likely to rely on default_do_language;
so I don't see the point of carrying an extra query to tweak the
behavior in a way that isn't even obviously an improvement.
