My browser console is spammed with these messages, that honestly seem useless to me.

I'm seeing this today. The browser console is full of these messages. Anything I should collect to help here?

This message used to be rare and very useful for debuggnig. But in case of mapping to HTTTP/3 it is not that useful.
I will look into restricting when we show this message, we do not need to show it if AltSvc map only to HTTP/3 protocol and he host name stays the same.
I will write a patch.

This is usually the case for HTTP/3 mapping.
The messages are useful only if a request is routed to a different domain name.
