In what way is it bloated? IIRC, the executable is less than 2MB, and without plugins it uses about that much memory too.
But I was rather saying that if a program has 600 pages dense manual (vimbook) it is certainly far from Unix philosophy of small utility doing one thing.
Damn, it has built in file explorer and remote editor (netrw).
Size is not really a good indication of "bloat" IMO. There are 683 syntax highlight files, 7.8M in total, but you don't load most of that and it's just "idle" bytes on disk. Same for indent files, ftplugins, etc.
You could also save ~5M by not shipping translations, but is that "bloat"?
It's useful these things are shipped, and in the scenarios where you care about 35M of diskspace you probably don't want a full Vim anyway (and you can use vim-tiny).
Sorry but I think you're confusing Vim with Emacs, the editor with the unofficial motto of "a great operating system, lacking only a decent editor" because of the tendency for users to do many computing tasks inside of Emacs (like playing MP3s) that had nothing to do with editing text.
Neovim is a refactor of Vim with 30% less code. They got rid of obsolete platforms (sorry Amiga and OS/2 users) and many features that no longer made sense or were replaced with newer/better functionality [1].
