Comment (by tom):

 Is this saying that if a website says Alt-Svc: a.com, b.onion  we should
 use b.onion before a.com?  Doesn't Alt-Svc specify the priority to connect
 to be in the order provided?

 Why do we need to do that? Can't the website put the onion at the
 beginning and UAs (should) know not to connect to it because it's a
 reserved domain?

 Or is the problem that UAs (Chrome? Edge? Safari?) are dumb and will spin
 trying to connect to the .onion so a website is forced to put them last?
