I'm surprised that nobody brought up yet that pressing i is rarely the only way to enter insert mode. As a vim power user, I use a, o and c (after different types of selecting some part of existing text) at least as often. That would make the clutch useless in the presented form, so I'm skeptical that this is actually being used.

Using the clutch either as a full esc replacement would make more sense (send esc on tap down, send nothing on release). Or inverted, send nothing on tap down but send esc on release, and have the user train that they subconciously tap the foot down upon entering insert mode by any means.
