Bill's exactly right here. From Section 3 of RFC 4035:

   A security-aware name server MUST support the EDNS0 ([RFC2671])
   message size extension, MUST support a message size of at least 1220
   octets, and SHOULD support a message size of 4000 octets.

So EDNS0 support for the part we care about most, message size, is already in draft-iab-2870bis as a side-effect of the last bullet of Section 2 of draft-iab-2870bis.
