I have this confusion reading the issue comments, so if one of the
servers is updated, and other server(s) in the replica are still old,
then self heal deamon would work, without the fix?
From the comment , I understand that the new node self heal deamon
If the above is true and the fix is to be at MD5 till <condition> then
that is a must fix before release, as there is no way to upgrade and
handle heals, and hence not get into split brains later as I understand.
Where am I going wrong? or, is this understanding correct?

I can take care of this, no worries. I need the information, so that I
do not misrepresent :) provided any which way is fine...
