MIDI rpn/nrpn messages combine 2 midi cc parameters to get double
resolution, 14 bit.
The answer to your question is that many of us are not using MIDI at
all to receive data from sensors or whatsoever, programs like Pure
Data can receive any kind of numbers over different protocols (HID,
OSC etc etc) so no need to get int o the MIDI bottleneck resolution.
