Hi! Applying mortar under the cement board would be extra secure yes, but it would also mean that your whole floor including tile is stuck to the subfloor. You wouldn’t be able to remove your tile without tearing out the floor to the studs. Most of the time you see mortar being used under tile which would either be on cement board or directly on a second layer of plywood (I wouldn’t do this in a bathroom). Using the cement board specific screws for this project, the cement board is very secured on it’s on.
shouldn't you apply a mortar bed under cement board? I believe both durorock and hardibacker include that as a required step.

Yes, yes you should. Skipping steps could result in cracked tiles.
