I think [SRV] works like an SPF record containing a single 'a'

It's a bit more subtle than that. A SRV lookup give you an IP address list
(the result of an A and AAAA lookup on the SRV target domain name) as well
as some auxiliary data. CSV uses the auxiliary data for authorization
information (yes, no, dunno) and the addresses for authentication. SPF
doesn't distinguish authentication and authorization.
However the end result is roughly the same, but CSV is more efficient.
