I wouldn't say he's stepped up. It's all a reactionary response to Neovim. I dont think we'd ever have async in vim if it weren't for the neovim project.
That being said I hope they pull an io.js and merge taking the best of both vim and neovim, whatever that may be.
you know what? I'm prepared to cut Bram Moolenaar a lot of slack given the goodness he gave us for 20 years through 7 versions of one of my top 3 pieces of useful software.
neovim will most likely merge good features from vim 8, but I find unlikely that the opposite happens. To be fair, I'm actually okay with that. One of the reasons neovim is where it is right now is because they forked it and because they keep it forked. I'm not sure how fast it would improve if neovim merged back.
Well, at this point in time Amiga and MS DOS should probably go.
They're served decently enough by older versions and I doubt that any machine running those has the resources for features provided by newer Vim versions. Even if they do, the OS support for these features might not be good enough.
If you know how vim-dispatch works, you'll know that it just opens up a split in Tmux/Screen or makes a new tab/window in your terminal emulator to run the command "asynchronously." While it does work, it's definitely a hack and not a feature of Vim.
