 discussing in Make/Core slack].

 If the revert does indeed solve the editor regression of a broken
 experience, then I support doing the revert.

 What about performance?
 [56896] provided a [https://github.com/WordPress/wordpress-
 develop/pull/5455#issuecomment-1757470060 2.5%] to
 [https://github.com/WordPress/wordpress-
 develop/pull/5455#issuecomment-1757532144 3.3%] performance gain for
 rendering the TT4 home page. The revert could mean these boosts will be
 lost.

 Performance is indeed important.

 But in this case, IMO a broken editor experience is the more critical
 consideration. Given that RC1 is today, I think a revert is needed.

 **Next steps**

 @bernhard-reiter prepared a [https://github.com/WordPress/wordpress-
 develop/pull/5509 revert patch]. Test report(s) is needed to further
 confirm the regression is resolved.
