Yes. It's part of a pattern I've noticed that I do not understand.
WotC has specific internal design principles that they use, and they almost never tell us what they are.
Some of these have been mentioned during the playtest. One of the early UAs told about "ribbons" in a sidebar, which was a revelation to many of us and now is just an understood thing in the fan base. Very occasionally a designer mentions some other similar principles. And sometimes those of us with lots of time for it can reverse engineer what appear to be (occasionally pretty precise) design principles.
But, in general, they don't tell us these things.
This is baffling to me in today's society and RPG environment. Is someone in upper management directing them not to share "trade secrets" for fear it will reduce their bottom line if fans know how to create content just like the official team, or what?
I mean, we have content from plenty of other places showing how you can do this in RPGs, and third-party creators providing alternates for official 5e D&D that work fine. But WotC can't just tell us what rules they are using for design so we can be better informed in our own work? This would literally make them more money, and most people here understand why so I'm not going to go into it. This is the 2020s, not the 1950s. It's ridiculous not to have more transparency here.
