No this is not necessary. To those of us with more than 2 radios... often the case when active on VHF/UHF... it is just necessary to be able to easily select which radio is Radio 1 or Radio 2 as a start. This is implemented in most competitive logging programs.... hot switching more than 2 would be even better... usually radios VHF UHF have their own antennas/amps so the SO2R RF switching is not necessary... however I like your idea for expanding the LPT control. I can imagine many useful functions such as routing the Mic or Key as well as RF routing.
