I appreciate some of the new features have that been added to full-site editing, but sometimes there is too much priority from core developers on creating new features instead of some polishing some long-standing issues.

For example: responsive images within Gutenberg are still largely still (visit https://github.com/WordPress/gutenberg/issues/6177)

Some of that thread comments are now out of date but I've outlined the next steps at https://gist.github.com/skorasaurus/a01249d4302226bf12c80dd979322303
