Another advantage of doing a catversion bump for v10 is that it lets
us add a new SQL-callable function (or two). I would like to add a
function to solve some of our discoverability problems around variant
collations. We now agree that we should not add variants at initdb
time, but Peter E's concern about where that leaves the
discoverability of the variants (phonebook, emoji, pinyin, and so on)
is a concern that I share.

Similarly, it would also be helpful if users could inquire about both
ICU version, and the corresponding CLDR version, using a new view.
That way, they could easily find the right CLDR version/standard,
which is where all the customization stuff is actually documented.

Any thoughts on that?
