I manage a large corporate network of WordPress sites. One of the strengths of WordPress now is the ability for us to lock down the design while allowing the authors to easily add content. We can (relatively) easily reuse, migrate and repurporse content because we don't use page builders.

I realise that this isn't the use case for the vast number of small sites out there, but the corporate and government world is subject to much stronger restrictions.

I would hate to see that capability lost from core WordPress.
