TBB plugin: T2W-OE - tor2web onion everywhere.
Fork HTTPS-E.
Maintain list of known t2w's.
Plugin update from tpo.
Matching engine rewrites t2w URL's to onions in TBB before the fetch.

They may not wish to if they want to return a single result per IP, and an
IP could be running more than one proxy (tor, i2p/cjdns exit, vpngate,
plain old vpn service, whatever), it's not generally possible to tell which
proxy emitted traffic from said IP, nor is it reasonable to require tor exits
operators to not participate in other networks.

Great for advertising statistical demand for anonymous access to
clearnet web operators, bad for blocking.

TBB should conform to Mozilla. Though it's a unique header, currently
unused by web operators, that's only for a while. If any such thing, it should
be a toggle, default off. You don't want to be unique unless you have to,
and it's unlikely even 1/3 of clearnet operators are programmatically
exit-aware, with fewer programmed to block.

Which is fine because it doesn't disclose any bits about the user to
clearnet, the disclosure to the onion is still anon and moot, and the
user can go direct to the onion if the onion blocks t2w.

Other proxies, vpn's, chains, whatever between t2w and the exit may not do this.

Yep.
