Are the subdivisions really used?  When i compile

{ \compoundMeter #'((2 3 4))  \repeat unfold 20 c'16 }

I get 8 sixteenths beamed together and then 12 sixteenths beamed
together (with no subdivisions), while i'd expect that every four
sixteenths there would be single beam insted of double beam (to be
precise, i'd expect a single beam between 4th&5th, 12th&13th and
16th&17th notes).
If this is unclear, i'll post an image when i'll get back to my
Lily-enabled computer.

BTW, when i searched for "compound meter" on the web, virtually every
place i found said that compound meter is a meter in which beats are
not divided in two.  So, for example, 12/8 is a compound meter
(because it consists of 4 groups, three eights each).  Constructs like
(2+3)/4 are called additive meter, complex meter etc.  Are you sure
that compoundMeter is a appropriate name for this function?
