block theme FSE – save changes to the theme?

I’ve done a lot of digging into the subject and looks like they were working on some updates to Gutenberg that would allow them to be saved onto the filesystem: youtu.be/8Vj_Oh6jMHw?t=281.

But those efforts were later abandoned: github.com/WordPress/gutenberg/pull/40385, as adding that support into WordPress core was complicated.

I then found this plugin that lets one do just that – save changes back to the theme and more: github.com/WordPress/create-block-theme.
