My point is that we need to keep both tables until the major bump.
Minimising the differences between them keeps the runtime impact as
small as possible. I am all for reducing the difference further, but
until the major bump, the old table won't go away.

We don't use _CTYPE_* in mklocale? Only the rune version.
