Absolutely. Except for two things.
Firstly, the Heresy series is a chance for many of those same authors to do something else, which is what they want to do, and are encouraged by the editors.
Secondly, what about the people who don't much like that author's portrayal of Faction X in the past? Because their voice matters just as much, and in some cases, they're pretty significant in number.
You think Y should do Z. I think A should do B. That Guy thinks M should do N. In some of these cases, the numbers are a little out of whack. There's no consensus even on a small forum that "Joe Joeman must do this faction because of his work in the past" let alone across all the forums, or the fandom itself.
That's what I find interesting. When people are so utterly behind one author that they reject another out of hand. I've seen it happen when they say no one else would do the Night Lords in the Heresy as well as me, or the Blood Angels as well as Jim, or the Ultramarines as well as Graham. For every one of those opinions, you've got ones to counter it - it's just difficult to bring the fact across sometimes that people don't understand that their opinion is just their opinion. Yeah, you loved Series X. Not everyone did. Yeah, you hated Book Y. Not everyone did.
For every 1 instance of "Aaron shouldn't touch the Word Bearers", I've seen a hundred saying they're glad I'm doing it instead of anyone else. That opinion is no more objectively correct than anyone else's, even if it's one that's a boon to see. I figure it's all about perspective: like you said, some authors should be considered highly. That doesn't mean no one else can touch the faction, because that would be poisonous to the license, and make for some dull reading after a while.
