That's because we went to great lengths to minimise it in pgAdmin 4.
It's mostly confined to template selection for SQL now.

OK. From my perspective though, I have to ensure that what we offer in
the community is a good experience. If it's not appropriate or
necessary to support a feature in GP, that's fine - but it needs to be
disabled to prevent users reporting bugs to us

Can you do a rough assessment of how many 'features' we'd be likely to
need to have the PG driver advertise? That would give a better idea of
the extent of the work involved.
In principal I'm not against the idea of having a function in each
driver that allows us to check for the presence of a given feature,
including by-version as required. What I'm against is that becoming a
mess of spaghetti...
