I gave this idea a moment of thought.  It would be easy enough to 
introduce 'display block only for the following roles' - but I'm not 
entirely sure how one would go about setting permissions for this.

I don't think that just anyone allowed to 'administer blocks' should be 
given the power to decide who (what roles) gets to see blocks.  So I 
figure that you would have to grant permissions to a user to be able to 
see that specific configuration option within the block configuration page.

So, being a complete drupal permissions newbie, I suppose my question is 
- what would be the best way to go about doing this?  Would adding a 
local task to the configuration page for this specific setting be the 
way to go? And add a perm for 'administer block visibility by role' (or 
something similar) and control access to the local task based on that 
permission?

Let me know if that sounds right - or point me in a better direction and 
I will see what I can do about baking a patch for this feature.  (No 
better way to learn about something than writing some code for it ;-))
