Oh hmm, it looks like things are a little more manual than I'd thought!
PropertiesUtil.Util.tokenize and PropertySource.getNormalForm massage the data,
but I had thought there were direct string replacements for a few property
names that I can't seem to find (perhaps I imagined them?). Given we already do
some key-manipulation, I think it's a reasonable place to define mappings from
old to new key names.
