I kind of doubt that there will ever be many of them, but if we start
to feel like there's a lot, we could invent abbreviations: single
feature names that clients can ask for that are defined to represent
a particular set of older features.  But I'd argue that those sets
should be groups of related functions, not "whatever random stuff
exists as of Postgres 27".  I think it'll be highly useful for clients
to declare which features they want, rather than leave people
wondering exactly which features this client intends to support.
