VIM clutch does not seem to prevent mode errors, though. For that pedals need to have feedback. I.e., if one hits 'a' out of habit or accidentally, stepping consequently on the insert pedal would predictably enter 'i' character. That would be avoided if the pedal changed to pressed state depending on mode.

That said, for me as a pianist the idea of mode pedal looks pretty awesome. It just needs to be developed a bit further.
