We use a fully automated process to "refresh" our farm of linux build agents. This includes a full tear-down of the filesystem and binaries, and re-installing all build tools, JDKs, etc. This ensures that individual jobs and plans don't degrade the system overtime.
We keep the Agent name and ID the same for historical reporting, but would like means to purge the existing capabilities from our process. This allows us to retire old capabilities/versions without the need to manually click, and confirm, dozens of individual capabilities on ten's of agents.
A DELETE call to a REST URL for each agent's ID would be amazing useful for our support of commodity agents.
