If this needs to happen on every request, a NewRequest event subscriber
is probably the way to go. And you can either just change
request.path_info and/or request.script_name or you can use
request.path_info_pop/request.path_info_peek to help you do that. Once
you change path_info and script_name, path_qs, path_url, and url should
be derived from your changed values. Traversal uses path_info
exclusively to do resource lookup, FWIW.
