Is there a reason why maxima shouldn't have orthopoly instead of
specfun? I haven't tried it yet, but I would think it's not worse
than specfun.
A couple of things I wish specfun could do. Perhaps orthopoly can do
this?
o gen_laguerre(n,0,x) = laguerre(n,x)
o gen_laguerre(n,1/2,x) = c*hermite(2*n,sqrt(x))
o various other relationships
Not sure if automatically doing this is a good idea or not, though.

I'm not sure, but I think it's beneficial that jacobi_p isn't
simplified. While hyp.lisp isn't always smart enough to return
jacobi_p with suitable symbolic args, other parts of hyp.lisp or
hypgeo.lisp might be confused if a hypergeometric function that should
have simplified to jacobi_p was expanded out to polynomial instead of
a jacobi_p function.
But I also haven't looked at hypgeo.lisp much either, so I could be
totally wrong.
