There should be something like the popular extensions list, but with verified working extensions for Orion. For now you need to download a working version from Popular Extensions and then disable updating for it to not get overwritten by newer version that isn't compatible. This however means that the extension will never be updated and there is no way to know when a new compatible version is available.
It would be pretty much a mini extension store for Orion. You would install for example Bitwarden (Let's use this as an example since the latest version doesn't work properly) from it. It would pull the latest verified compatible version with Orion and install it. Once a newer version is available and vetted working, it would be pushed into the store and Orion would pull the newer version automatically.
