Totally anecdotal, but I've been in a number of tenure-track hiring meetings at multiple universities and someone always brings up the idea of "pedigree". As in, "X has a good pedigree" etc., as if that's an argument for hiring the person above and beyond their track record. So at least in my personal experience, these things do enter into the process.
Of course, the process involves a lot of other variables too; there are plenty who don't talk about pedigree, but there's often someone who will point to it as a rationale.
I hear similar whispers about federal grant receipts, etc., in that people who get stamped with approval in the form of training fellowships, predoctoral NSF awards, etc. are seen as sort of "understanding the system" etc.
As I think of it, I can think of lots of other "in-group signaling" in various domains, so maybe it's not unique to academics. But that cuts both ways when you're talking about exclusivity and "old-boy" networks.
