I think you allude to this with your comments on optimization, but DNS resolvers will generally, just like CNAMEs (which nearly all DNS names begin with these days) will return additional records to reduce any round-trips for getting the record at the end of the SRV.
SRV records are great, and would reduce antiquated reliance on ports for specific services. This would be helpful for HTTP, especially with things like TLS, where certs cold be returned without SNI being used.
