Comment:

 If I understand you correctly, having more than one SOA in an RRset is an
 error, but we have code elsewhere to catch that, and the unittests are
 considered useful. But we don't have code elsewhere to catch multiple
 CNAME or DNAME RRs.

 Anyway, the question for me comes back to this: Every line of code has a
 cost - to write, review, test, maintain, and execute. Is the added
 security for RRset::addRdata() (for CNAME and DNAME, minus SOA) worth
 either the man-hours or the milliseconds? If yes, then merge and close as
 fixed. If no, then close as wontfix.
