I noticed the same with Severance (also Apple TV). After every episode, there is a short director commentary/crew interviews about random episode specifics or more higher level thoughts.
I liked it quite a bit.

It is funny that these things often just get released on podcast platforms and aren't really integrated into the streaming service.
Especially since this show, and the shows mentioned in these parent comments are all produced by the platforms they got released on. So they also have a whole lot more control to actually integrate this extra content.
These streaming platforms often state they are competing to keep you on their platform consuming things, and it seems odd to me that they wouldn't want to try and capture people for longer with these kinds of extras. Especially since as the other user indicated, these would be much lower cost to produce and license compared to the original content. And for someone who really enjoyed what they watched it would be a pretty appealing extra to have.
