Because programs gets broken in other case. Almost any current system
strcoll usage suppose ASCII-compatible charset and produce unpredictable
bugs otherwise. We are not ready to free-form collates yet.

Because it is not in the form suitable for FreeBSD. Do you check other 
collates before making your variant? Do you notice their similarity in 
some aspects?

I preserve as much of your variant as I can, making it ASCII
backward-compatible. I can't see how it can be very broken.

I am not sure what your question is exactly. There are certain rules. I.e
when you sort ASCII file, it must remains the same as with LANG=C for
compatibility reasons. Your variant not pass this requirement. I don't
remember why I don't reject it initially and let it in.
