I think it may be a bit premature to be seeing a big uptick in block themes in the org repository, but it’s not premature to ask the question.

After all, block theming is not yet available in core. When it is, we should see block themes starting to trickle into the repo. At what point will the growth start to curve sharply upwards? Well that’s the million dollar question. When some of the bigger templating plugins such as WooCommerce properly support FSE, that almost certainly will help.
