If CREATE DATABASE referred to a collation in the template db,
either that collation already exists, or the user would have to add it
to the template db with CREATE COLLATION.
initdb already populates the template databases with a full set of
ICU collations through pg_import_system_collations().
I don't quite see what change you're seeing that would be needed in
initdb.
