I think the rationale about it is worth to read:

IMHO this exception has clear historical reasons.

The discussion in the rationale captures the essentials of the dispute
the last time this came up as a bash bug.  The invented `collating
element order' and the Posix requirement to use it are useless without
a standard API to query it.  Without that, one is left with either the
standard APIs that understand locales (strcoll, etc.), or native order.
Bash and glibc made different choices here.

Roman is arriving late to this fight. :-)
