If you only read the goals section, I can understand that many things
regarding this is unclear.

The issues you describe may be of importance but they have not been among the
goals for this remapping of keys and therefore it is not included in that list
of goals. It isn't stranger than that.

ON is left unassigned (as much as possible) for a reason, and *that* is stated
among the goals.

Personally, I don't care that much for cancel either but I don't feel very
strongly about it. I would say that it is quite fine as long as we
consistently allow it all over and it is used the same.

Besides all that, the document is not meant to cover everything in regard to
what keys that do what, it only covers a vision of how the main screens could
function.

The cancel functionality was added for a reason. If you would need to keep it,
how would you instead suggest that we deal with SET vs CANCEL ?

I wouldn't necessarily call that overloaded. OFF gets you out from the screen.
Exactly in what state it leaves the things you were doing in the screen is
somewhat undefined all over and I don't see this huge inconsistency as you do.

Still, I too would rather have OFF not restore the original value. I just
can't come up with a more intuitive interface than having PLAY set the value
and without having it set, we go back to the old one.
