The behavior of collation sequences is implementation-defined. So as
long as you can put the behavior in words, it should be OK.
It would seem, however, that the behavior of a certain locale name
should be the same with or without ICU, so perhaps some locale renaming
might be needed, but that is speculation on my part.

Yeah, pretty much the whole point of that code is to avoid collating
stuff.
