Right - the "always add at end => always get conflict on merge"
anti-pattern, whereas ordering things (members, files, fields, methods,
whatever) in some coherent way related to their meaning or just simply
dumbly alphabetically would mean additions typically happen all over the
list, so contemporary changes seldom collide and merges are easy.

But we digress,
