You will note that this dryer is before the top-mounted lint screen so you either put the lint filter box on the back or had the lint blow outside through a short vent. Here we have an installation where the dryer is against the wall, under a window and the window is open. That must be delightful, lint-wise, if the prevailing breeze is toward that side of the house, but don't let reality enter this picture of laundry utopia where the lady wears a hostess apron and heels to do laundry and, from the looks of her eyes, might have partaken in a little mental lubrication somewhere along the line.

Actually, you are right in the case of certain Frigidaires, which could store the water in the bottom of the cabinet, but not through a complete cycle.

Your preference for the multiple belt drive and speed reduction pulley system does not make it better in anyone's eyes but your own and you can't extrapolate from the Maytag system to pronounce superiority for the WP system which even used another belt to power the blower. Both machines sacrifice drum depth for space needed for the pulley arrangement.  Sometime, look at old Kenmore dryer manuals and check drying times. The inefficiencies reflected in the long drying times and the need to overcome them with high BTU burners and 8 KW heating elements say all that is needed about the design of these dryers, unless John Lefever modifies one with felt strips to prevent a significant amount of the incoming heated air from bypassing the tumbling fabrics in the drum and slipping behind the drum to the exhaust port. So much heated air passed behind the drum that these dryers did not have lint buildup in long vent runs because so much of the exhaust was quite warm and dry so by the time the air coming out of the dryer was steamy, the vent pipe was warm enough that condensation and lint deposit within it was not a problem.
