That's odd. I heard that spin-drain prevents lint/scum problems. ???

Maybe, to some degree? But I’m not sure how any machine that does not overflow rinse could prevent the stuff floating on the rinse water from settling on to the laundry as the water is drained.

I also have a Whirlpool from the same year- 1984- and it essentially does the same thing, just without spinning at the same time. Water level drops, and the stuff on the surface settles on to the load. 🤷

I recall an advertising graphic that illustrates Whirlpool's premise for neutral drain reducing lint/residue atop the load is that the drain port in the outer tub has the water level in the outer tub drop slightly faster than the level in the spin basket, which has an effect of pulling water through the perforations of the spin basket which in turn has effect of pulling floating lint/residue out through the perforations to minimize it from settling onto the clothes.

In my experience neutral drain leaves scum rings around the agi and tub, and anything floating on top of the water is strained through and thus redeposited on the clothes. Spin drain has always provided me with the best results.
Which brings up the interesting point that the original WP direct-drive design was spin-drain, and the question of why'd they go to the effort to develop the Rube Goldberg neutral-drain mechanism if spin-drain is superior.
