I suppose it's OK as long as real-world clients are happy.

Good to know.  I'll make a patch ASAP and maybe some tests
down-the-line...

If you're using a .psgi config file to customize the middleware
layer, you should be able to access `our' vars through it:

diff --git a/examples/public-inbox.psgi b/examples/public-inbox.psgi
index e017b2fb..36cd8b57 100644
--- a/examples/public-inbox.psgi
+++ b/examples/public-inbox.psgi
@@ -14,6 +14,7 @@ use strict;
 use warnings;
 use PublicInbox::WWW;
 use Plack::Builder;
+$PublicInbox::WWW::INBOX_RE = qr!\A/([\w\-][\w\.\-\+]*)!;
 my $www = PublicInbox::WWW->new;
 $www->preload;
 
There's a bunch of `our' vars which happens to be accessible across
namespaces, some with the intent of being tweaked by end users,
some for internal-use only.

I can't remember what reasoning I had for making $INBOX_RE
globally-accessible, but I'm fine with it used in this way.
