I believe that marketing-wise it is a considerable problem for WordPress that many people still think that it is just a blogging platform instead of a complete CMS. At the same time, the idea of "blogging" seems to me a bit obsolete, at least compared to what it used to be 5 or 10 years ago.

That's why some times I wonder whether it would be a good idea to completely remove comments and possibly some other features (even posts and taxonomies, I would dare say), offering them as core modules instead, more or less with the same way that Jetpack handles its own modules.

Of course I don't know if something like that would be realistic or even desirable, or what the possible implications might be, but it would seem to me like an interesting topic for discussion, at least on a theoretical level.
