The draft specifically disclaims the semantic/pronounceable aspect.

IMHO, there is *no* reason not to advance both .zz and .internal:

   - .zz (for general non-human use cases, like automatically generating
   locally scoped, globally unique names, a use case I have for
   resolver/forwarder identity)
   - .internal (for humans)

Or basically, for the pronounceable use case, keep that separate and do in
another place, don't really care where/how (e.g. .internal.arpa or
.local.arpa or whatever).

If the delegation is to AS112, I think the typo attacks become a
diminishing issue. Not sure, though.
