Eli even argued that `string-collate-lessp' is strictly worse compared

I think, Eli is afraid of the following sort of inconsistency
(string-collate-lessp "z" "ö" "de_DE.UTF-8") ; => nil
(string-collate-lessp "z" "ö" "sv_SE.UTF-8") ; => t
Mixed language example: U+0049 LATIN CAPITAL LETTER I vs. U+0406
CYRILLIC CAPITAL LETTER BYELORUSSIAN-UKRAINIAN I
(sort '("Івана" "Ivan" "Термін" "Вони")
(lambda (a b) (string-collate-lessp a b "uk_UA.UTF-8")))
("Вони" "Івана" "Термін" "Ivan")
(sort '("Івана" "Ivan" "Термін" "Вони")
(lambda (a b) (string-collate-lessp a b "en_US.UTF-8")))
("Ivan" "Вони" "Івана" "Термін")
