You mean a simple, utility-specific, easily-implementable specification goes
against the grain of basic software design principles? Is that like saying a
hammer is a bad choice for driving nails because it's not flexible enough to
apply paint to walls?

I guess my question is: Why do you want greater extensibility? What problem are
you wanting to solve? Is the specific problem that DKIM attempts to address,
not important enough and not complex enough to justify having a simple,
tailored solution?
