There's a tiny amount of bikeshed as I think you can make both work,
but I think it's better to avoid query strings as there are at least
some costs involved in supporting them. But, to me, I think doing
everything as query args makes the module a tiny bit more complex that
I think we could avoid.

Caching is also a factor here - as if we use query args, we have to
explicitly override and specify which responses are cacheable; but
some caches are a little stupid and don't consider query args as ever
being a differentiator. Also, from a server admin perspective, if we
are explicit about verbage in the URL path space, it makes it slightly
simpler to configure balancing/proxying. For example, I'd like to
simplify the pass-through logic for the write-through mirror to just
look at the URL space - looking at the bodies of the request is lame.
Ideally, if we stick everything into URL space as paths, you could
configure the load-balancing/write-through entirely with a cluster of
ProxyPass directives - ProxyPass won't look at query strings, IIRC.
