We already kind of have this possibility, though (via 
vc-annotate-toggle-annotation-visibility). It's not enough because dates 
and names are useful, and even having tooltips won't cut it.

The main stopper, I think, is the "togglable by attribute" UI (well, and 
also the implementations for extracting more granular data for each 
backend).

That would be nice.
