I recall back in the XPI extension days it was possible to host your extension on your own website and have Firefox offer to automagically install it as if it were from the normal add-on site. I believe Chrome also did this for a short while in the early days, too. Surely even with the severely gutted and locked down WebExtensions they have now, it would still be possible to do this again and independently provide your own add-on, or even host an alternative add-on store along the lines of what F-Droid does for Android. You can put all the scary security warnings you want to scare off the unknowledgeable masses, but at least you'll provide some vector to allow niche users with niche requirements to add and trust a niche repository of their niche add-ons.
