In reply to Andre.

The ThemeForest question is something I may explore more in depth. However, I think they will be just fine. The last I checked, there were more theme authors there than on WordPress.org who were embracing the block editor. Many will likely be ahead of the game when it comes to block patterns too.

When block patterns drop in core, I imagine there will be a footrace to see who can ship the best and most patterns to end-users. Patterns will be another marketing bullet point. Authors there will be leaders and building features that other theme authors will want to replicate.

I know ThemeForest has caught a lot of flak over the years (much of it coming from me), but the site and its authors know how to market theme products.
