Is Calling Python from MATLAB the solution to Fortran MEX compiler compatibility across platforms?

Some thoughts,

With the ability of MATLAB calling Python files directly and passing variables from one to the other, is this the route to take instead of building Fortran MEX files? One could compile exisiting Fortran routines into a library to import into Python.

Will this approach impact perfromance in comparison to calling MEX funcitons directly? Anyone using this approach?
