That is more or less correct. The API (protobufs) needed for frameworks to
use this feature will be part of 0.23.0. I imagine it will take some time
for frameworks to adopt this feature (i.e., a framework has to explicitly
opt in to revocable resources and mark a task as revocable). As of 0.23.0,
only Mesos containerizer (not Docker containerizer) has this support.
