The thing is, I've seen totally bogus "Impact:" statements.

It just makes things look more official, without actually guaranteeing 
that it's any more correct. For example, I've seen impact statements to 
the effect of "cleanup", when (a) it wasn't and (b) it did other things 
too.

At that point, it's just distraction and wrong.

And in fact, "cleanup" seems to be the most common one. Along with other 
totally useless ones like "fix build" or just "Fix" .

Gaah. 

Doing a

	git log -p --grep=Impact:.*lean 

shows several "cleanuips" that are anything but. Those "cleanups" fix 
build errors or actually change code. The "Impact:" statement is actively 
misleading, adds absolutely _nothing_, and detracts from the real issue 
and the real message.
