I don't think that's "all that's needed". Here's what's actually needed.
Upon PTT closure the transmitter must get ready to send CW code
before the first keying pulse arrives in order to avoid chopping it,
like it does now. Minimum "PTT setup time to key down" shall be specified.
Upon PTT termination the transceiver must switch to receive as fast
as possible and as clean as possible, disregarding the "CW QSK Delay"
setting. Also the AMP KEY line must get deactivated as fast as possible,
disregarding the "External T/R" setting. Minimum "PTT hold time from key up"
shall be specified.
