> Not all of the WebExtension API surface is currently supported; there's a long tail of infrequently used extensions that require non-trivial engineering effort and often cross-team coordination to implement.
While API support in GeckoView/Fenix might be incomplete as compared with Fennec, then again the API support in Fennec was equally incomplete when compared to Desktop, and yet with Fennec there were no restrictions in installing addons.
> There's also front-end/back-end engineering required to fully expand existing UIs into a proper "store" experience.
I suppose you could always try polishing thins up even more, but given that addons.mozilla.org already had (actually still has) a mobile view/responsive layout that seemed perfectly adequate, this still seems somewhat strange.
