I have tried incorporating Gutenberg in my custom site builds several times in the past year but I just haven’t found a way to do it successfully and reliably. If WP are focusing on block based themes now, they should just ditch the customizer entirely and focus on improving block customization (the customizer is a nice idea but it’s time to let it go- it isn’t very well implemented or useful today).

The code and methods of Gutenberg keep changing and it’s hard to commit to using Gutenberg for a custom site when so many important things required for customization are not prioritized (such as wrapper blocks which only came out a few months ago).

Creating a custom Gutenberg block is extremely time consuming compared to flexible content blocks using acf and the time investment isn’t worth it at the moment. Ideally, I’d love to be able to quickly wire up some custom blocks and build entire sites using these templates and I assume this is what the WP team are going for, if I had a say.

Lastly but most importantly simply using Gutenberg is hard for both writers and developers. I don’t agree with splitting paragraphs into separate blocks and it’s cumbersome to have to hover, drag, and rearrange a page with a lot of content. Honestly the UX is unpleasant and feels unnatural- the reliance on hover states is bad and everything feels too floaty. Imo WP should take a page out of Notion’s UI because if they don’t improve GB soon I do believe Notion has the potential to take a significant chunk of WPs share if it can be successfully integrated with jamstack powered sites in the future.

Anyway that’s my two cents, I do think GB has potential and block based themes sounds like a neat idea but rn the idea and execution needs A LOT of work.
