pacman leave optdeps behind the user did not install [SOLVED]

Is it expected of pacman to leave behind an optdep (and its dependencies) of another package that the user did not implicitly install?  Example is deluge:

Installing deluge and then removing it leaves behind a number of python2 dependencies that the original install operation pulled in related to python2-twisted.  These were not present on the system before installing deluge but python2-twisted is an optdep of another package already on the system (avahi in this case).

1) `pacman -S deluge` pulls in 21 python2-* dependencies
2) `pacman -Rs deluge` only removes 16 of them.  The remaining 5 need to be removed by removing python2-twisted.

After these two transactions, python2-twisted and its dependencies are left behind and they were not present before installing deluge:

# pacman -Rs python2[TAB]
python2                 python2-constantly      python2-twisted
python2-click           python2-incremental     python2-zope-interface

Full logs of 1 and 2 above:

Re: pacman leave optdeps behind the user did not install [SOLVED]

It's expected as far as pacman's features go. Last time I checked, pacman only did one thing with optdepends: It understands, that they are deps of a package, if they are being installed --asdeps, so they don't show up on a -Qdt style orphan check, nothing more, nothing less.

Re: pacman leave optdeps behind the user did not install [SOLVED]

This has nothing to do with optional dependencies.  There is a dependency cycle. https://bugs.archlinux.org/task/41031
