PublicInbox::NewsWWW fallback lets //$host/$message_id work (no /r/).
It can be run as a standalone PSGI, too, see examples/newswww.psgi

At least it works on my Tor .onion mirror of lore:
http://lore.czquwvybam4bgbro.onion/ and
http://rskvuqcfnfizkjg6h5jvovwb3wkikzcwskf54lfpymus6mxrzw67b5ad.onion/

To get /r/, you can use the "mount" directive in the
Plack::Builder DSL as shown in example/newswww.psgi

That said, I seem to recall lore.kernel.org/r/ existing before NewsWWW,
so maybe it was something else, too.  (It may have even existed
somewhere on kernel.org before lore)
