The reason Maxima doesn't make such a transformation is that the 
notation is inadequate for the job.  It is intentional.


You can do this:

gradef(f(y),h(y));

then diff(f(g(x)),x) is shown as  h(g(x)) * diff(g(x),x).

There is no widely accepted notation for "derivative with respect to the 
first argument of f".  I believe that there are packages in Maxima that 
make up such a notation, but they
are not used by the ordinary "diff" program.
