Yes, but discrimination is unsupported and avoidable.

No spoof.

Quite the presumption :(

And as a result, Tor Browser owns up to its ID with no spoofing, as Tor 
Browser users appear a Tor Browser users.

Or using the internet.  What if the OP is tired of being rejected from 
visiting sites due to IP badlists and uses said proxy to appear like a 
clearnet user so as not to be restricted.  Google products (except for 
Google Images) require this.  Ix Quick and Startpage feature this.

Again with the presumptions :(:(

Will you link to the use cases and threat models in the documentation?

Fail often to succeed sooner :)

My thought is that this is being mentioned in multiple places and, if 
there is any merit to undetectability, we should challenge it fully to 
see; not settle with what we have and use "good enough" as an argument.  
I suggested a formal proposal as the next step.

Wordlife,
Spencer
