might not want to hear the QRM from the other station (which your guy might
well not be able to hear due to prop.) until you complete whatever it is
you're sending...
Just hit the foot switch (connected to PTT) and you'll mute the RX until you
let up on the footswitch.
The scenario you articulate here is EXACTLY why many CW contesters prefer PTT
on CW. Listening to all the QRM while you're transmitting, and having to focus
on your own sending while doing so, gets exhausting after a while, and when
you get mentally exhausted, errors ensue.
This is the way virtually all IKenSu transceivers work today. In other words,
PTT has priority. It's as simple as that. Pressing PTT puts the rig into TX
state, muting the RX, until it is released. Doesn't matter if you're doing QSK
or semi-QSK. Hitting the foot switch overrides that functionality instantly
for as long as it's held down (but no longer).
I don't think this is quite what the Elecraft implementation does, as it
sounds like you have to actually be in "PTT mode" by manual operator setting
in order for PTT to put the rig into the CW TX state. This is probably fine,
as most ops will either prefer to use PTT CW or one of the other modes, and
won't feel the need to be able to override in QSK or semi-QSK modes. But the
"override" method is how most rigs work today, at least the ones I've used.

Yes, a little clarification (or language lessons) seem to be
appropriate here. How is 'Transmit mode' different from
'transmitting already because the key was tapped'?
Does closing PTT when in QSK mode inhibit a return to receive until
the PTT is released? - that is the only thing I can think of.
My guess it that yes, it will inhibit auto-return to RX upon key
release.
It certainly seems that the generation of RF is controlled by the
paddles in any case (except for the new TX inhibit condition). A
few things were clarified, but confusion still reigns high in my
mind.
