Why yes, there is now a market niche for a new kind of cupboard or shelf, to go into all avionics workshops. It has a compartment for mode C transponders and another for 25 kHz radios. Demand is expected to be considerable.
And I hear some saying that there was no real need for 8,33 , only too big a part of the available 25 kHz channels are reserved for authorities that don't really need them and use them rarely, if at all.
But it seems like now is too late to re-open the debate.
