In FL-8530, I described failing to install spidermonkey with the new update of polkit. The reason I didn't have it installed in the first place was because I had a local version patched to not use spidermonkey, but instead the lighter duktape javascript engine. I found this patch a few years ago as I was trying to rid my system of python2, back when spidermonkey still didn't have python3 support, and had completely forgot about it until now. I already have the new sys-auth/polkit-0.119 with that optional patch in my public-overlay, but would like to make it official and, seeing as I completely forgot about it, can attest that it works without issue.
