You can leave this in historical repository, and strip current repository
from abandoned work, by the way.

As it was said somewhere in this thread, you can use tags (tag objects) for
that, i.e. tag each of the abandoned branches, explaining why branch wa
abandoned for example, remove head refs, and move tag refs to
refs/abandoned or refs/tags-abandoned/ or refs/Attic/ or in refs-abandoned/
(the last has the advantage to not be included by default in any command,
even when --all is given)

There is no need for new flag. If you give --all flag to the gitk command
line or the list of commits option field, all the refs in $GIT_DIR/refs/
would be included. If you will use refs-abandoned/ instead, it would be
enough I guess to give refs-abandoned/ or refs-abandoned/*. Of course you
would need some change to visualisers to mar abandoned branches in
different way.

gitweb as of now uses only refs/heads and refs/tags; markers are taken from
$GIT_DIR/info/refs or "git-ls-remotes ." (i.e. all refs/)
