That is correct.

It seemed to us that the URLs parameter, which can be used to configure 
the HTTP paths dnsdist will accept DNS queries on, was causing a lot of 
confusion, so we decided to just accept DNS queries on all paths for DoH3.

I don't think this is related to the urls parameter, wouldn't you rather 
happen to have a response map [1][2] for DoH handling the redirect? 
Response map support hasn't been implemented for DoH3 yet, and seems 
there was no feature request for it in our tracker I just created it [3].
