Well, what I actually propose is a BAI for "symmetrical extra".
Assume that its rafsi is -xax-, and assume that I understood the
jax- proposal [NB I am getting some batches of Lojban list mail
THREE WEEKS late!]: then the lujvo would be jaxyxaxyckaji.

My objection still holds, for the reason given. I suggest that instead
of having x4, x5, x6, x7, x8, etc., we have a BAI that means "x+",
and is used for adding infinitely many extra, symmetrical, places to
selbri that need them.

I sort of glork the intent, but I don't see that it answers my objection.

As far as I can tell you understand it right. But the hearer doesn't
know how many places there are, if unfamiliar with the adicity of
the selbri in the ka clause.
