I don't think it is certain to stay, as they seem to avoid commiting to the extension capability in their future Versions of Firefox for Android.
So AFAIK it might be that they want to get rid of it.

I got the idea from this [1] reddit comment made by someone with an Mozilla Employee flair:
> [...] There is not yet a concrete plan (feature) to bring Web Extensions to Fenix. That does not mean it is not going to happen. It does mean we have some things to figure out first.
and this [2] github issue where they state
> Not for MVP, will look at it for further versions
I fear that what they'll want to figure out first is whether not implementing them will hurt adoption.

Second, in that very github issue that you linked, look at this comment: https://github.com/mozilla-mobile/fenix/issues/574#issuecomm.... Also, transition from Fennec to Fenix won't happen until feature parity. The MVP is just that, the MVP.
Finally, GeckoView does not use the WebView interface, specifically because we want to build richer experiences than the WebView interface offers.
Thank you for the reply. It's really good news to hear that full extension capabilities will continue to be supported!
I was worried by the very comment you linked, as "users will get the experience they expect" sounds carefully crafted to not say anything at all.
