This is conceptually similar to [accompanying-questions], but limits all 
questions to share a QNAME. The result is a more concise payload and 
simpler processing logic at the expense of an ability to request e.g. 
(www.example.com, A) and (_443._tcp.www.example.com, TLSA) in one query. 
I can imagine many scenarios where such queries would be valuable, 
though, and am suspicious about the tradeoff (which essentially supports 
only A+AAAA queries) being worthwhile. [accompanying-questions] had some 
[issues] of its own to work out, but seemed to fall at approximately the 
right level of flexibility for allowing clients to query for more than 
one tuple.
