I think I already answered that: I think that basically pulling all the
(extensive) functionality of music mode into \chordmode with a slightly
different syntax and duplicating all the accessors is a maintenance and
user complexity sin as compared to pulling all (limited) functionality
of \chordmode into music mode with a slightly different syntax and
reducing it to none.

Because we can.

That's certainly the case for \repeat tremolo as well: you know what
you'll get.
And what if you see \chordmode { c,4:1/c c g,:1/g c } in the input
(which is basically how you put bass notes in now if you really must)?

If we make a separate mode for all the simplest cases of music input,
then try to fit in all the complexity for the harder cases in different
ways, I don't see that we win. Lilypond has a _lot_ of material, having
to learn it a dozen times in different ways for the sake of making a few
isolated cases _look_ simple helps nobody.

There is currently no sane way of entering bass/chord sequences and
chord combinations. That's not something I want to leave untreated for
prospected 12-18 months. I am acutely embarrassed that there is no
reasonably efficient and natural way to enter accordion music in
Lilypond.
