As a user, I like this idea. I thought that I was excited about full-site editing, but when I opened a block theme and tried to start creating pages, it was a bit overwhelming—if I could start by adding template parts into a more-familiar experience, I would have been a lot more confident.

For the one site that I am creating from scratch (my first ever), I am using Chaplin, a block-friendly classic theme, and am getting more comfortable. I also work on an Elementor-based Astra-themed site (but new pages that I create don’t use Elementor, but the WordPress editor; much less confusing), and a couple of other sites with different configurations.
