Wordpress Copying?

I could be off but over the last few months I noticed that Wordpress has added "blocks" to structure blog posts. Yes I do have some clients that still utilize Wordpress so I'm forced to be at least acquainted with the system.

I've been posting some blogs for clients and I noticed Wordpress is trying to not use a WYSIWYG editor and they are moving to more of a structured set up. At least that is what the latest iteration of Wordpress appears to be to me. I just find it interesting. It might be they like the Perch approach to structured data?
