[Elecraft] RX antenna & carrier-operated relay

Hi guys,
   I was thinking of a possible firmware improvement related to the
carrier operated relay.
I use my radio on a small lot and recently I added a short beverage
antenna for low-bands receiving. My main activity is single-op contesting.
Because of the interaction between the tx antennas and the beverage, on
some bands I have the COR (carrier operated relay) activating when I use
high power.
I know the good solutions, but my point is different.
As I have the COR activating only when the RX Ant input is selected, why
doesn't the K3 firmware disable it when pushing the ptt?

In fact, when I push the ptt I don't need the RX-ant part to be active,
as I'm transmitting, and -at least in my setup- I have no other
rigs/devices that need that input (I mean, no in-band receivers and so on).
Instead of using external relays (ptt-activated) that cut out the rx
input when I am transmitting, why the K3 firmware just doesn't disable
the RX ant input on its own (and re-enables it if needed when releasing
the ptt)?
Maybe I'm missing something here, or that could be a nice improvement
for a next firmware release.

Thanks for any comment,
Ciao 73
