Yeah, this isn't anything like the great canon wars of 1994.
But on the topic of canon
this page, which is a source of the wikipedia article, comes to the conclusion, that it is a matter of interests, even inside the Lucas empire.
On the one hand you have Lucas himself who really seperates Star Wars into two worlds and on the other hand the guys from Lucasfilm Licensing who have many levels of canon.
I personally favor the later model for
my Star Wars, but I am also of the opinion that when you discuss something from G-canon, that you shouldn't slip into lesser sources for explaination. Only for speculation.
That said, I like the speculation given in Dark Lord: The Rise of Lord Vader, that goes along the lines that because the clones have a limited time to live many academies are built where unaltered clones are grown as well as their templates are trained, because it would take too long for them all to be ready.
