I think part of the disagreement is that modern applications have muddied the water. Not all modern engines have been designed for top side extraction, but if someone sees/hears someone doing it successfully they might assume that top side extraction works well for all modern engines. This might lead to an assumption that it works for older engines.
I was skeptical with top siders until I saw them called for by a factory manual and removed the oil pan to confirm that it did work quite well. I'm all for using them when they are called for and designed for. Outside of those conditions I'm with you, its lazy and ineffective.

Yes, due diligence is key. Apparently you did the experiment, like I did, and not just pass along hearsay and opinions.
I agree it’s dangerous to assume it works for all.
But this thread is about the 616/617, and it works fine there.
For any other vehicle, the simplest test is to do an extraction, then pull the drain plug and see what comes out. Modern scopes could be inserted to look since now tiny ones are available super cheap and are a good thing to have in the toolbox regardless. Dropping the pan is the ultimate test, but some vehicles it is easier said than done.
