I guess that just like it happens with voice repeaters, there'll always 
be someone wanting to access a digi from down a mineshaft with a 1W 
handheld and a rubber dummy load antenna.

I'm in the throws of setting up my old FM97 (an FM92 that thinks it's a 
91) to go in the car (after a 5 year break). I'm still thinking about 
how to be able to select aprs or voice. I suspect that whatever I do 
will revolve around using the 8 pin DIN socket for the TT3+. That socket 
already has tx audio (albeit requiring high-level), muted low-level rx 
audio and PTT, and pin 8 (spare) can get switched +12 for the TT3.
