That's ENUM, not DNS SRV, and again, not necessary. I know of very few software SIP clients that don't allow SIP URI dialing. No need for numerics whatsoever. I can dial alphanumeric user@host from any number of clients.
No this has nothing to do with ENUM. In general, one cannot absolutely assume name@domain is reachable at a SIP server running on a host named 'domain'. That's inflexible and is like assuming only host 'domain' will accept email for name@domain. There may not even be an actual host named 'domain' or if there is, it may not be running SIP. Ignoring SRV RRs also means your SIP client/proxy or SBC wouldn't be taking advantage of the resiliency provided by alternate target servers.
