I don't believe it's any simpler for SELinux to do the allocation
than for the infrastructure to do it. I don't see anyone's head
exploding over the existing infrastructure allocation of blobs.
We're likely to want it at some point, so why not avoid the hassle
and delay by doing it the "new" way up front?
