It just shows the dep chain, not a reason or warning. I am saying it
just needs a warning. A reason why it did not remove. When not using
versbose/-v

Warning like
"Not removing package A as it is a dependency of another package"

This just shows the dep chain, no reason why. Its left to the user to
interpret, since not removed. Its needed by other stuff. But that is
not said explicitly.

# emerge -cav gcc

This is worse and just needs a message, warning, as to why it was not
removed.

Either way, as I stated, if using -C, you get warnings with profiles
and sets, but not with deps. Deps should have a warning as well.
