I like this. And specifically I think that trying to set speed in
those files must generate a fatal error.

Isolating and enforcing exactly where the setting is allowed is of
course a neccessary step in the right direction.

Usability may be slightly worse in the immediate term with such a
change, but having the infrastructure in place to allow verifying
that settings can only be done in the correct fashion in the correct
places is a fundamental requirement for improving usability *later*
e.g. with an algorithm that selects a safe default frequency.
