Ah I see. The v8.1-m reference I had looked at didn't have the same optional instruction suffix. IIRC we don't use VGETLNi32 for MVE, it goes via MVE_VMOV_from_lane_32 instead, and the D reg variant is an alias of the Q reg version (and doesn't mark the size as optional in the same way). They do look like they were there in v7m though.
