If you're able to download a script, what's to stop you from getting vim-gtk
from the repo after boot?

vim already comes with GRML; For me, the 7MB isn't necessary when regular vim
works just fine. Other than better mouse and tab support, Does it offer some
compelling additional functionality over regular vim? vimdiff is already
included for diff support; I'm not sure I'd need/use vim-gtk over regular vim
even if it were included.

Maybe, but If you want a proper graphical text editor, I'd rather go all the way
and use geany; I don't feel vim-gtk is compelling enough.
