Comment (by helgatheviking):

 >Reiterating my thoughts, a significant amount of work would be required
 to refactor the menus screen in the admin to be properly performant.

 Does it have to be completely refactored to be "performant"? Knowing that
 the primary work is being done in the customizer, couldn't we aim for a
 patch that was more like "good enough" or "better than what we have"?

 >The biggest issue that this fixes is unblocking things like the ability
 to add custom fields to nav menu items; however, that is already unblocked
 for the customizer UI and can be addressed in #18584 when those that need
 said hooks are able to provide input there.

 This isn't unblocked in the Customizer, unless I'm misinterpreting what
 you mean by unblocked. Currently the admin is the ''only'' way for users
 to add post meta to menu items via plugin. So my plugin's UI doesn't work
 at all in the Customizer. Myself and a few other plugin authors have taken
 to implementing our own common action hook as a work around for the lack
 of a core action hook, but users are still at risk for running into the
 $_POST limit described by this issue.
