I don't find such an ambiguity acceptable at all.

That is a plausible argument, but if it is valid then it then suggests that ALL places where we have a zo'e-like elliptical word, we need a zi'o equivalent as well (co'e, do'e, do'i, fu'u, ge'e (the zi'o is the computer attitudinal %^), and ju'a, with others possibly not noticed). And why not have a zu'i for each of these as well? Complete semantic refinement a la And requires beaucoup new cmavo, none of them necessarily justified by usage. (And Jorge will be caught between his demand to eliminate lots of rarely used cmavo that JCB and I added for analytical reasons - and his support for semantic refinement which will create more such.)

Didn't you recently note that tu'o can grammatically be used in cases
where mo'ezi'o can't go?

mo'ezo'e actually. The usage in question was tu'o as an elliptical digit value, as in pasosotu'o (1990's), or retu'o (20-something). I'm not sure anyone has posed any correponding use of tu'o=mo'ezi'o wherein it could not in fact be replaced by mo'ezi'o. But I'm not going to argue against the split, because we do indeed have to support the admittedly kludgy RPN unary operator grammar that led to tu'o in the first place. I can't think of a situation where the ambiguity between vacuous and elliptical leads to pragmatic ambiguity, but if there is one (and I can imagine there could be), that is an argument for an operand zi'o.

But I start to wonder whether it would not be better to add a cmavo paralleling kau that could attach in the same way to any word in a selma'o and make it a vacuous member of that selma'o. That would require a CLL change since the vacuous RPN operand would be "PAzi'o", assuming zi'o became that vacufier (I'm not proposing this, I think - we could add new word, and leave the old ones as redundancy in preference to changing CLL). We could add another word to this set for your "only possible value", if it is justified - I suspect it has usages other than for quantifiers, and indeed sounds a little like one meaning of "only".

I'm not pushing for any change at all of course - but if I have to accept that a fix is needed, let us make sure it is the right one.
