That is not what I had intended to imply, rather that the collection of
music symbols encoded today might have left out a considerable number of
lesser-used (not: never-used) symbols.

The emphasis was on making sure that attested symbols don't dribble in;
the recommendation would be to make a concerted effort to collect and
process them in the largest chunks that are reasonably feasible.

The reason they are not present in Persian notation, is that one usually do not transpose, but it is easy to do that in modern music computer engraving programs, so it might be nice to have them for that reason.

I could see additions like that if "modern music computer engraving
program" suppliers were making a representation that this would solve a
real or closely anticipated problem (and that they and the community of
their users would expect to be able to use such symbols).

A mere observation that these might "logically" exist, I would find much
less compelling.

Again, if there's a consensus by practitioners that such notation is
required, that would be one thing; mere speculation about them being
logically necessary doesn't carry the same weight, because we know of
many examples where actual practice ended up with illogical notation.
