FWIW this is the sort of thing that I was +1-ing into core.  (With the 
additional possibility of it being placed into the default theme.)

That's why I said in my earlier post "I can't see a reason not to do 
it", because at the end of the day it could help out the average user, 
and any power users who didn't want it would find it trivial to 

To address a comment that was made earlier in this conversation, as to 
why this has not been brought up as an issue before.  The answer to 
that, for me, is that we never had stuff like this before -
