The biggest thing that makes DWs so absurdly efficient is that they can prerinse ALL items in a load no matter the size with like 3/4 of a gallon.
Even with low flow kitchen faucets, imagine rinsing the ENTIRETY of a full DW load in 30sec or less.
The one thing where one has to know ones DW or alternatively pre-rinse is highly pigmented foods.
Tomatoes, currys, certain greens etc.
If your DW does run a COLD prerinse for sure, those aren't an issue usually.
If it runs off of hot water, it heats the prerinse or maybe is known to likely skip the prerinse for sensor reasons, that can easily stain plastics.
I personally don't care much about that to be honest.
But others might be bothered.
But beyond that... I run my DW once a week since I live alone, and don't prerinse anything.
Only thing I do since recently is that I soak the glasses I use for my fibre supplement by just leaving them filled with water in the sink overnight.
If that fibre supplement isn't fully hydrated before being left for days, it can stick so much that even a 90min main wash dosen't completely remove it.
