Let's not exaggerate the 'problem' here. Merely accepting more than one
SRV record doesn't come anywhere near the level of complexity of SPF --
in fact it never occurred to me _not_ to handle the multiple-record case
even when I was implementing CSA purely in Exim's configuration language
(http://david.woodhou.se/eximconf/include/acl-helo-csv)
My suggestion is that a domain can have one (1) CSV record that can
point to a single name that can have as many A and AAAA records as
needed, and there we draw the line.
I don't see the point in making that restriction. You'll get all the SRV
records in one query anyway; all you have to do is deal with them if
more than one exists. That really isn't hard, and it's the expected
normal behaviour of DNS records. I see no reason to deviate from that.
