True enough. In SfePy, we describe problems (PDEs) to solve by using 
regular Python files, which is nice and easy, but the interface, i.e. 
all that can be in those files and understood by the solver, is rather 
tightly coupled with what the solver can do - its implementation. The 
topic of PDE solvers is really very broad, even if we restrict "just" to 
the finite element method, and there is not a silver bullet interface 
that would work for everybody.

Just my 2 cents, as a guy that writes finite element codes for 
not-so-small time.
