Have you given any thought to cold crashing the starter while it is at high kreusen and decanting it?
I tried that with a lager, the yeast didn't drop out in the fridge, there was still some Krauesen at the top the nest day, and the starter was cloudy from the yeast. You might have to get closer to freezing to crash some lager yeast.

Yeast are somewhat resistant to flocculation when there are still sugars in solution. I would not be surprised that it takes significant cold to get them to drop at high krauesen.

You could make a starter out of second runnings and pitch the whole shebang in 18 hours.

This works well for me.  I take the late mid to tail runnings or on light lagers, just the whole wort as collected and use that as my starter...works great and I don't rush the pitching this way - I just have to post a note to myself to remember to pitch the yeast (I brew early in the day, so my starter is usually rocking nicely by bedtime.

I'm willing to bet that a lot of the off flavor concerns come from pitching a large starter that was allowed to finish out and had plenty of chance to oxidize since the yeast had finished up and the starter was allowed unfettered access to oxygen. By pitching at high krausen, the yeast are still plenty active and oxygen pickup/oxidation of the starter wort isn't a concern.

Exactly. Too many people are making unhopped, oxidized, DME beer on stir plates, as opposed to propagating yeast. If you match your SNS starter wort to the underlying malt character of your recipe (e.g., Extra Light Pilsen DME if the main base malt is Pilsen Malt) and adjust the recipe appropriately, one liter SNS starter pitched at 12-18 hours shouldn't have a perceptible impact on the beer. I don't see how it is much different than adjusting a missed OG by adding DME.
I probably brew differently than you. If that makes you angry or somehow ruins home brewing for you, maybe you need a less stressful hobby than making and drinking beer.

Alestateyall just motivated me to pull a couple slants of 2352 out and start propagating them for my next brewday. Got my mini flasks in the autoclave now.

Using Saccharomyces' size rule of 4 times larger, I've got a couple 100ml pyrex erlenmyers to shake 25mls like it owes me money. (Step 1)
