It's 2016 wiki:

"Internal snapshots to images which support internal snapshots (QCOW2
& QED) are not expected to be supported initially."

"By making the snapshot-file argument of the monitor and QMP command
optional, that could be used as a request to make the snapshot
internally instead of to an external file. However, without live block
migration of an internal snapshot, there is no way to make a backup of
an internal snapshot while still leaving the VM running, so this
feature is not planned at the present. For now, the snapshot-file
argument is required, and only external snapshots are implemented."
