After thinking more about it, I do not see grounds for reverting.

It works per RFC. It adds value. It's documented precisely.

Sortability in cs_CZ only stands in a way for this format to become "the one 
UUID format to rule them all" instead of canonical in the future.
We should let IETF WG know that digits and letters are not always ordered as 
they expect. Hopefully Sergey will handle this.

BTW, thanks to Alexander and Masahiko for pushing this to finish line! I'm 
listed as author, but they done 99.9% of work on making this functionality.


Best regards, Andrey Borodin.
