The times I open new file vs times :e line is already in my vim/bash history is tiny. And that tiny amount is handled fine by vim's filename completion.

There seems to be a big divide in usage between gui vim'ers who are probably doing one window/ide thing vs terminal vim'ers who probably have multiple terms/vim's open and use unix/cmd line as their die.

Note I make value judgment as to which is better (I'm sure people vary and so should their tools). My point is you should figure out which one you are and filter vim suggestions appropriately
