Such a machine generated description would contradict the intention of
Rubin Simons for this description entry. IMHO this description entry
should be used for user-provided descriptions only. For any other
purpose (like a history log) another entry should be added.

ACK.

This will be easy to support in the ESX driver, because a virtual
machine has an free-format annotation field where this description can
be stored.
