I'm not going to dig through the austin-group archives to try to
distinguish which of the two parts of the quoted behavior (inherit, or
otherwise not set) was the source of anyone's objection. I concede
that the explanatory paragraph in the rationale did not call out
either of those behaviors.
The point is that none of what we're discussing is an agreed-upon standard.

I mean the simplest form of what zsh refers to as "scalar" internally.
Yes, that's ordinarily representable in C by "char[]", but in the
abstract that doesn't matter.
On the other hand, the shell language doesn't really deal in anything
else. Everything is designed around file descriptors and argv
(char[][]) and performing implicit string splitting/catenation, and
except for nameref in ksh there's no way to pass pointers around.
