Hi Dave,

I saw your v1 interaction after commenting but, I still think commits 
that say "this removes a data structure" should elaborate more.

"This structure is no longer used since commit: 12charsubshahere" or 
"This structure was never used and should be considered dead code"

I generally hope the intention of my commits is clear from the code with 
the commit log adding whatever context or elaboration on top.

So that's what I'm suggesting here. A bit of commit log sugar on top 
which elaborates on and justifies the change.
