If you have a habit of hitting TAB RET, then you are, in effect, expecting
TAB to complete to a complete match, so that RET will open the existing file
whose name matches. With that expectation, incomplete matches throw you off.
In that case, you want TAB to complete only against existing files, no? Then
why not bind `file-file-existing'? That's what it's for.
