Yes, efficiency is clearly critical. This is where optimization of the
switching waveform can be part of the solution. Elecraft's
implementation for CW keying is a raised cosine.

In the installation on which I consulted, this wiring WAS implemented as
twisted pair, based, I suspect, on the QST piece by K1KP and W1RFI.
