Possibly, though would have to see data, I guess. I feel like a lot of people are just curious about Vim and spend all their time in insert mode anyway. I have seen a bunch of those questions around "how would I do this without exiting insert mode" questions, though I'm not sure that having a more accessible escape key would change all of their minds. The "I want to use this new thing but I'm only interested in using it in a way that I'm used to" mindset is rampant among programmers.
