It depends...
On the dishwasher. Machines without 1) good water distribution, 2) ample water use, 3) a long hot main wash, 4) a self cleaning fine filter, 5) maceration, and 6) ability to process reasonable quantities of food particles and flush them away; will always require various levels of pre-rinsing. There is no way around it.
There are only a handful of dishwashers that ever satisfactorily met all 6 of these categories. The Whirlpool Power Clean filter modules, Whirlpool built Kitchen-Aids, MOL/TOL Maytag Jet Clean dishwashers, *GE GSD1200-GSD2800 series dishwashers between 1984 and 1994, GE Profile model Z GSD4900Z-GSD3400Z, were the only dishwashers ever produced where dishware could be loaded without any pre-rinsing. Whirlpool's point Voyager system could also fit these categories provided soil levels never went above moderate.
*The 1984-1994 GSD1200-2800 series had an Achilles heel where the steal macerator would break off with time or a hard object like an olive pit went into the sump. GE specifically designed for such contingencies in that 1984-1994 sump boots had a dammed "pocket" to the left where an unpulverizable hard object would be kicked into the side holding dam and remain there until retrieved. Unfortunately the idea did not work out so well in that the pit would cause the steel macerator to break off in the process.
Pictures for future readers inexperienced with vintage GE dishwashers.
That leaves the majority of dishwashers past and present requiring various levels of pre-rinsing which defeats more than half the purpose of having a dishwasher. People just don't know any better to say or realize otherwise. People never saw the limitations of tall tubs when they arrived because they were pre-rinsing already, and many of those with Power Cleans and Jet Cleans were already conditioned to pre-rinsing. The few that made the switch from no pre-rinsing to tall tubs saw the light, grumbled about it, but when they found that tall tubs were the only machine available on the market they had no choice but to alter their habits while the rest of the world routinely gaslights their lived experiences.
To live in modern humanity is to have both your sanity and intelligence invalidated.
If everyone was like me the Whirlpool Power Clean Module with ample water use, time and heat would make up 95% of all residential dishwashers including those in apartments, condominiums and rental properties.
