SSAC wrote about DNAME in March 2006 in SAC-009 ("Alternative TLD Name Systems 
and Roots: Conflict, Control and Consequences"):

Unfortunately I can not remind myself that recommendation has been followed...

On top of this,  SAC-053 ("SSAC Report on Dotless Domains") where SSAC have the 
following recommendation:

Let me remind people SSAC recommendations do only have weight based on the 
quality of the report itself. There is no requirement for anyone to follow the 
recommendations. That said, ICANN Board must take SSAC (and other ICANN AC) 
advisories and recommendations into account, i.e. at least explain why the 
advice was not followed.
