Why are applications separate from groups?

Hello

I was setting up a new forum this week, and whilst doing so, I realised the group page is essentially useless. I am only using a forum application for this particular use caseand nothing else in this instance, so the group page is just showing forum questions.

There's actually nothing I need from the Group page, it doesn't have the Forum -  Ask a Question widget for users to search existing questions before posting (I may have missed that so forgive me if it should be there). It exists just to surface content from the forums application.

So, I guess my question is, why are content types created as applications rather than being part of the group container? I have groups in my community that exist just to hold applications and it creates an extra layer of navigation for users.

I would appreciate any strategical insight here.

Thanks

Oli
