Some of them will ;)

Cert infrastructures can make linkphisher proxies harder and
gives options to users and operators as well as an actual layer
of traditional browser to webserver crypto. Disabling warnings
there for all of .onion doesn't. And certainly disabling them for
pinned certs and CA's wouldn't.

As before, extending TBB to skip warnings for HS pubkey signed
certs of respective single onions seems fine.

Your webserver can/should enforce TLS for that connection regardless
if it's on localhost or the other side of the planet via clearnet or
some other transport.
