(Nit: all database default collations are deterministic.)

I agree, but I think there should be a way to see the whole picture in
one command. If nothing else, for repro cases sent to the list, it
would be nice to have a single line like:

   SELECT show_default_collation_whole_picture();

Right now it involves some back and forth, like checking
datlocprovider, then looking in the right fields and ignoring the wrong
ones.
