I was asking for a way to remove a frame parameter. I don't see any
remove-frame-parameter, and `modify-frame-parameters' can add and
modify values, but not remove them, IIUC.

They should not be conflicting. The docstring of
`make-variable-frame-local' says: "Buffer-local bindings take
precedence over frame-local bindings." I would expect that, after

 (make-variable-frame-local var)
 (make-variable-buffer-local var)

any (set var VALUE) would set a buffer-local value.

It is a bug nonetheless. We should take note somewhere.
