Nowadays, I would agree. I've never seen any use or mention of this
DEC-HANYU encoding in the wild in 11 years, so probably the number of
users of a locale in this encoding is nowadays between 0 and 0.01.

I propose that you merge in this change into your patch:

        * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always.
