I think the reason for that hostility is that, since it was decided software needs to be made and software developers are the only ones who can make it, tasks that don't involve making software may be better handled by others. No one has solved contract writing, and of course developers need to contribute sometimes, but the less time they spend on contracts, the more energy that is put into delivery of working products. Working products soothe stakeholders better than developers detailing why there's no product yet. A lot of success with Agile comes down to having great administrators/managers/etc who are capable of dealing with as much of the surrounding efforts needed to make software in an organization as possible.
