Yes.

I think this is too much work, and as you said, not that many people
might be using this feature.

The only thing is this: gnus-bookmark.el was good to get Gnus bookmarks
and *only* them.  This will go away with the new gnus-bookmark.el.  So,
since the new feature of bookmark.el will help many modes provide their
own ways of setting a bookmark, I think it would make sense to have a
"type" key in the bookmark record (similar to the annotation), and be
able to list bookmarks of a certain type only.

C-u C-x r l [Prompt type] Info RET 
  => list bookmark of Info type

C-u C-x r l [Prompt type] Gnus RET 
  => list Gnus bookmarks

If you think it is a good idea, I will do it.

Ok, will do this.
