I understand that, but it seems like the most frequently-used features (eg. cosmetic filtering) are possible in MV3. So a version with those features included would still offer value.

Correct me if I'm wrong, but it seems most of the missing capabilities are power user features - even by HN standards.

It's of course your discretion if that's something you wish to work on. I think a Minus and Plus version (or "Regular" if you prefer) offer a nice option for users to choose between. But I understand if the development overhead of managing two versions cannot be justified.
