Thanks for bringing attention to this discussion! It's been really informative to hear all the varying thoughts/questions/concerns/etc. It's encouraging to see how the knowledge and awareness around FSE is continuing to grow. I see momentum around issues like this as a reflection of that, along with the concerns people have.

I mainly wanted to comment here to re-share something I said on that issue so that folks have clarity there. This issue being added to the 6.0 project and being open at all with reference to 6.0 does not mean it's for sure happening for 6.0. This issue is meant to reflect a decision needing to be made and a place that people can follow along as the discussion unfolds. The decision is the to do -- not the removal of the label outright.

I wanted to make that clear as I fear that accidentally I somehow gave off the wrong impression. It's part of why I changed the title to start with "Discussion" to better match the labels and situation at hand.

Separately, if you're an extender (whatever form that takes), I deeply encourage you to comment on open issues or open your own around blockers you might be running into in order to adopt various features of full site editing. Doing so will help us move with confidence when the time does indeed come to remove the beta label since it'll give the WordPress project the ability to address widespread concerns sooner rather than later. I'm @annezazu on WordPress.org slack if you want to chat. I'm off work for the next two weeks but will respond as soon as I can upon returning.
