This wishlist bug has been open a year without any activity. I'm going
to move it to "Opinion / Wishlist", which is an easily-obtainable queue
of older requests that have come on.

In case you want to work on that, consider writing a blueprints [1] and
spec [2]. I'll recommend to read [3] if not yet done. The effort to
implement the requested feature is then driven only by the blueprint
(and spec).

NOTE:
The need for a "discover capabilites" API got discussed during the Newton summit [4] (but without a clear path forward IIUC).

  This information is quite misleading for the user.
  The message should come as "Pause not supported for vmwareapi"
