No plans - no.  But it is rather obvious that the number of ways two things
can be non-logically connected a) has never been well-analyzed semantically
b) well, the current set was discovered and not planned, and hence cannot be
said to neatly encompass the possibilities.

JCB had only one non-logical connector, which he used in a trivial way in
tanru and nowhere else.  We have ce and ce'o at minimum that have seen wide
and necessary use, in addition to joi - which encompasses JCB's connective
but may be being overstretched in current usage.

Adding to JOI is NOT something I would consider propsing before the 5 year
baseline ends, but it is an area that I expect will need looking at, even
if experimtnal xVV cmavo haven't already sprung up by then.

It probably would work, but I am never sure till I try it. And dual purpose
JOI strained the LR(1)-ness of the language beyond limits and we had to do
speciall fiddling to get it to work.  I don't think I could have justified
this if at the time I thought JOI was going to be even as important a part
of the language as it has become.  You can ALMOST justify a little sloppiness
when you are being non-logical in your connectives, was my reasoning.  But
the logical connectives are part of the "core" of the language, and ambiguity
even in a minimal sense, glares very severely in such a role.

Because as I said the semantics of the connectives has never been analyzed.
Actually, though, since you ask, I suspect that the LE for jo'u would have
many similarities to lo'e/le'e which focus on the commonalities in a
disparate set, which is what I THINK jo'u does.

Yes, but you are asking for errors and noisy-environment ambiguity, which we
can tolerate minimally in joi connection, but not in logical connection.
Pragmatics can usually clarify an error in JOI connection; I doubt that it will
be a srobust for logical connection.

But it wouldn't.  We could then move the respective sets of non-logical
connectives into JE and E, and eliminate JOI.
