Hi,

The @changed-deps set is useful, but it has limitations similar to the
@installed set [1], which can make it unsuitable for use when updating
the whole system.

In order to solve the problems of @changed-deps, we can implement two
new options that are analogous to --newuse and --binpkg-respect-use,
called --changed-deps and --binpkg-changed-deps.

The rationale for having separate a --binpkg-* option is the same in
both cases: depending on the situation, people may want different
behavior for binary packages. For example, just like
---binpkg-respect-use is automatically enabled if the user has not
specified --usepkgonly, we could do the same for --binpkg-changed-deps
(but allow the user to explicitly override the automatic behavior).

Please respond if you agree or disagree with this proposal.
