I've never seen Vim users do that. If I had to choose, I'd use Vim.
Its truly revolutionary when one thinks about it how much impact Vim has on terminal users.
(Neovim's plugin system is nice but I agree with ya that I also feel like some aspects of community often don't appreciate Bram because of the Vim vs Neovim thing from my observation) It's best if instead of treating it as Vim vs Neovim, we use the tools that we prefer and appreciate the tools other are using too and the contribution of one in another. Appreciating Vim doesn't make your appreciation for Neovim lesser, appreciating both can be great. Something which is hard within Editor space in general.
Rest in peace Bram.
Sure, switching might not be that troublesome, but I can tell you the first 48 hours or so will be painful, you'll insert stray ":" and "i" characters everywhere :)
