Tell that to LilyPond:

{ c'8[] }

is valid music.

You are presuming that LilyPond has some greedy "autoBeam" setting which
will be broken by any manual beaming instruction and will exclude single
notes.  Or that it should have that.

So how do you propose the minority should be input?

You are calling out significant savings in typing, but then the effort
for typing something like [] contrasted to \appoggiatura does not seem
all that large.

And we are talking about an incompatibility that can't easily be cast
into a convert-ly rule, so at the very least, scores relying on grace
notes without any beaming instructions remaining separate will require
manual changes.  And I don't know how this might affect things like
bagpipe music.
