That depends. If you have other mechanisms than dig to get data out
of your cache you don't need it. I would like to see it deprecated to
the level that no one relies on the query being answered with a record.
So even the resolver can answer with NOTIMP.

I can not see how there is a reason for a validator to issue an RRSIG
query, and I do not know of an validator that does this (there might
be). RRSIG is as complex as the ANY query as you have to look for all
resource record types and not just one. We don't need to include that
in this draft, but the complexity of the query is higher than a normal
query and the use of it is way lower (IMHO it is not needed).

Just two quick datapoints I got. On a recursive server farm that of a
medium ISP (that doesn't do validation, but has it server DNSSEC enabled)
out of a total of 15 billion queries a day there were 6 RRSIG queries 
and on an authoritative server for a DNSSEC secured domain that has 
around 2 million queries a day there were 7 RRSIG quries. So maybe we 
deprecate it before people use it more ;-).

So long
