Possible to block X-UIDH?

[gavin20]

So far the solutions I found from blogs is either use VPN or proxy. No other means to block? Github user lightswitch05 attempted an extension, however carrier overwrites the X-UIDH if it is already set.

Or just HTTPS wherever possible.

Interesting idea, but even if it worked, it would be just a matter of time before Verizon notice and take measures (overwriting). The same way I soon expect them or whatever other evil ISP to not insert their tracker id when a user fetches http://lessonslearned.org/sniff.

So there is not much which can be done by HTTP Switchboard, the HTTP header is inserted by the ISP long after the net request left the browser. In uMatrix I plan to have a user-activated switch to discard any http requests, that's the best I can think where an extension can help.
