I don't use Gramps to record DNA information, but as you haven't had 
much of a response I thought I would add a comment.

Using person attributes is a good idea.  A key of "Y-DNA Hg" and a value 
such as "I-M253" seems a reasonable approach.

Do you need to include "confirmed" in the value?  By attaching a source 
to the attribute you are indicating the result is confirmed. Inferred 
data will either lack a source or have a different source.

You could write a tool to find the MRCA.  A gramplet might be useful to 
display DNA details.

Perhaps it would be useful to write a GEP.  You could still prototype a 
solution using attributes.
