We already load all ward boundaries in scripts.js, which is going to be cached, probably. So we're actually adding bandwidth with this change, not reducing it.
I may want to show other ward boundaries in the map.
Nevermind, we're going to do this after all. But instead of merging the branch, which is littered with merge commits, I made the few small changes to the current dev branch. I'm closing then deleting this branch.
This branch may be irrelevant since:
So don't merge this.
