As you might have realized this file has shrinked a lot, and is eventually
matter to be go away, with all code encapsulated in modules. So I wonder whether
we can have a different mechanism, perhaps an option in jsHydra, to force load
modules?

Ok, I've implemented it as an option in JSHydra. This doesn't seem to be the
cleanest solution however. Usually, there is a dedicated entry point ("main"
module in Firefox) that will load all the other modules.

The new approach makes sense to me, but the only thing is it might make
https://issues.adblockplus.org/ticket/4047 more urgent.
