Yeah, I doubt that's worth the churn.

On that note though, we might want to consider just dropping it altogether in
v17 (while fixing the incorrect hint in backbranches)? I can't imagine
adminpack 1.0 being in heavy use today, and skimming pgAdmin code it seems it's
only used in pgAdmin3 and not 4. Maybe it's time to simply drop old code?
