I was hoping for a new section(e.g. “DISCARDS”) to be added to the doc file for the ‘devices_handle_discards_safely’.

Wasn’t 1.6.0 where discard support was added?  If so, 1.6.0 should just be “Add discard support”.  The new section should explain all the short-comings and issues with discards + parity RAID.
