I agree.  I tried the completions-highlight-modifications branch, but
unfortunately restricting a set of navigation keys limits the freedom of
using any navigation key for browsing completion candidates that is
available today.  What I mean is that currently it's possible in the
minibuffer to type <PageUp> (switch-to-completions), and then all keys
are available for selecting a completion: arrow keys, page scrolling
keys - even completion drop-down combo in browser's address bar allows
page scrolling.
