i was there when SRV was conceived. we intended it to be used opportunistically, like MX before it, falling back to AAAA or even A queries if there was no SRV. it can be added to any protocol at any time, including HTTP/0.9 clients to the extent there are still any of those around. SRV's rules are defined for a service not by the client. if we decide that web servers can be reached by SRV records, then any web client can start looking for the SRV that describes that service, falling back to whatever tin-cups-and-string it did before if it can't find the SRV it wants. in that sense mark andrews' HTTP SRV I-D from all those years ago should not have been controversial.
