When changing from object mode to face/edge/vertex mode the former mode selection remains selected. It is a bit annoying when you forget to deselect before changing because you can end up with both the brush and a face/etc selected so you have to deselect all. It's a minor thing, but it would feel better if changed.
I don't think there is any use for having hybrid selections? I've never had a need for it, at least.
It probably shouldn't deselect right at changing, but at selecting the first thing in the new mode.
Unsure if i follow, it's designed to only edit components of selected objects. You can't even enter component mode w/o object selection, deselection disables component mode automatically too.
