>During the deprecation period, we can keep this functionality via patch (since it's there for Enterprise). After V2 is pulled from store, we'll need to stand up our own extension store for manifest v2
Is it that simple? Brave has various proprietary bits, so it's possible they could maintain v2 support. Perhaps others know if this is feasible, from a technical perspective.
Until a chromium browser let's you use arbitrary extension stores, I don't think there's any fork that's divergent enough. And I haven't found one after months of searching.
I'm almost to the point of trying to do it myself.
