// You can't just do PathPrefix("/(r0|v3)") because regexps only apply when inside named path variables.
// So make a named path variable called 'version' (which we will never read in handlers) and then do
// (r0|v3) - BUT this is a captured group, which makes no sense because you cannot extract this group
// from a match (gorilla/mux exposes no way to do this) so it demands you make it a non-capturing group
// using ?: so the final regexp becomes what is below.
