Does NS5.0.7.1rc1 use nsIContentPolicy?

[GH113]

Hello!
According to Wladimir Palant, nsIContentPolicy causes performance problems with AdBlock Plus: https://bugzilla.mozilla.org/show_bug.cgi?id=1280368#c1
So I wanted to ask:
Does NoScript NS5.0.7.1rc1 use nsIContentPolicy? As far as I understand, according to this page https://noscript.net/abe/users.html, NS uses nsIContentPolicy at least for ABE. Also, barbaz here states NS does use nsIContentPolicy viewtopic.php?p=84506#p84506 but the post was written on Oct 5 2016 so maybe things changed since then?

I guess NoScript WebExtension won't use nsIContentPolicy because nsIContentPolicy API is not part of WE?
Also, bonus question: the latest beta of NoScript initiated preference migration, does that mean the release of NoScript WebExtension is close?

Yes

Maybe. Someone posted a near-future release date on mozillaZine, but they didn't name their source, so I don't know how credible the info is. I'll ask them and get back to you.

Oops, didn't see that GH113 is the author of the mozillaZine post, which that part wasn't intended to be serious.
