I've commented on this before, but the fact that policies can't be automatically applied to users in the same or similar way as the Email Address policy is really poor and inconsistent. If you seriously think organisations are going to WANT to manually change each user for a EAS, UM, or Managed Folder policy, you have got to be kidding.
At the very least it should be possible to set a default for all users.
With regard to Powershell, using this to set users is not a solution for many customers. They just want to set and forget ... and especially to keep the need to manage these things away from an already burdened Helpdesk.
This shows as much foresight as dropping the ADUC snapin - none at all. The product is great, but you're dropping the ball on the customer-facing components that really matter.
