The wifi implementation oscillated for a while between the current code
and something that looked like what you describe. While what you
describe is indeed easier for users, it was a _pain_ to implement and
maintain as every object had to access these variables through an extra
indirection. My experience is that it's much better to move the
variables to where they are used and rely on the attribute system to let
users access them.
