I'm not sure why we want to get into editorializing this.  We query ICU
for the names of distinct collations and use that.  It's more than most
people need, sure, but it doesn't cost us anything.  The alternatives
are hand-maintaining a list of collations, or installing no collations
by default.  Both of those are arguably worse for users or for future
code maintenance or both.
