Since I don't recognize the experimental cmavo, I can't comment. Using an
(apparent) contrast with an experimental cmavo is a rather weak
justification for another experimental usage.

The reason "na je" has not implied grouping is because it is called out
distinctly in the YACC grammar as a separate rule with no grouping, as is
NA JA NAI. But the parser rule is specifically that UI is absorbed into
the preceding token, which indeed means that "(na) (je)" and "(na) (jenai)"
will be considered identical grammatically.

I know you think that.

Except for the fact that NAI would not have consistent meaning in its
various incarnations.

But not the SAME meaning.
