Yes, the mozjs dependency is unfortunate, and trust me, we would very
much have liked polkit to use a different JS engine, or no JS at all.
We have been postponing this polkit bump for years due to this. But
this is upstream polkit's decision, and at some point, we have no
choice but to follow what they did.

If you look at the polkit archive, many years ago there was a patch
series posted to use the ducktape JS engine instead of mozjs. It would
be very nice to revive this work and hopefully bring it upstream.
Indeed, ducktape is 2 orders of magnitude smaller than mozjs I believe.

Is this binary dynamically linked against libmozjs, or statically
linked against it? The fact that it has the same size as libmozjs makes
me think it might be statically linked against it.
