I guess we'd need that when creating a database with a different encoding than the template databases, at least. About what's not ICU-aware, I believe the most significant part in core is the Full Text Search parser. It doesn't care about sorting strings, but it relies on the functions from POSIX <ctype.h>, which depend on LC_CTYPE (it looks however that this could be improved by following what has been done in backend/regex/regc_pg_locale.c, which has comparable needs and calls ICU functions when applicable). Also, any extension is potentially concerned. Surely many extensions call functions from ctype.h assuming that the current value of LC_CTYPE works with the data they handle.
