Maybe I'm missing something, but I didn't think there would be anything
terribly disastrous about having pg_import_system_collations() install
these descriptions as comments in v10 and then changing it to put them
directly into pg_collation in later versions. We'd have to adapt the
behavior of psql's \dO, but that's true no matter when we change that.

Agreed, but we can probably tweak that without forcing a catversion
bump.
