That ("firmware internally..." etc.) really sounds more like an
argument *not* to apply this patch ...

Everyone has their favourite BT coex control. We could possibly
implement this in our driver, but I'm not sure we'd *want* to, since
it's so far from what we actually do today.

Do we really need more than toggling it on/off?

Actually, I probably should've asked this much earlier - but what use
cases do you see for this? What can a user, or userspace application
like NM, really try to set here? It seems the use cases for this would
be rather constrained?
