I want to reiterate the benefit that underscore_names would bring. To be
clear it's not my favorite style, but it does have a very concrete
advantage which is that we have a very large subproject already using it.
it doesn't make sense to do a purely aesthetic move that not everyone is
going to agree on anyway, when we could do one with actual tangible value.
