I am afraid that would add too complexity and hence cost to include it
in the 'normal' programmer. But what's wrong with using two Wisp628's?
Or add a relay, switch it with the serial port handshake lines.

I use both approaches: I have a box that contains one wisp628 that
programs a second one, which programs an external target, which can be a
40-pin chips with wloader. Relays controlled by the handshake lines
direct the serial port to either of thye Wisp628's or the WLoader.

Optional components do take PCB area, which is a cost factor. And they
would need to be 'bridged' for normal operation.

Maybe I'll add some freely controllable pins of the connector, so you
could add an external relay board.
