Parallel in what sense? Ex and Ax bind the variable, i.e. together with
an expression F(x) they give a proposition.

The way we use the lambda variable, the expression F(x) remains open.
"le ka F(x)" refers to a function of x, where x is not bound.

{da} could be used for this job if it wasn't for its automatic default
binding even in the absence of an explicit quantifier. {ce'u} would serve
to block the automatic binding, but having {ke'a}, which is also an
unbound variable in relative clauses, there is no need to get into
such complications. In "da poi F(x)" the role of {ke'a} is precisely
the same as that needed in "le ka F(x)".

I would prefer that solution over the pseudo-quantifier, but I hate to
see a new cmavo for something that already exists and is actually so
rare. I don't think it's overloading. In any case, what's the rush?
If we find in practice that {ke'a} is causing confusion, a new one
can be added, but I don't see that happening.
