Add visibility option to hide posts from main index

I was wondering if there's a way to create a post that's won't be included in the feed, but without making said post unlisted. The post would be visible within its section's feed/web-index but not in the main feed or the home page.

Add status "unlisted-lite" to hide items from the main feed / index, but show them in sections, tags...

Would you consider getting rid of the “unlisted” status and implementing a “visibility” parameter instead?

Possible values for visibility: null/public, private, unlisted and custom/unlisted-lite?

A combination of "status: draft/published/deleted" and "visibility: public/private/unlisted/..." sounds like a good idea.
