Leaving aside all kinds of seeing aspects, can amateurs detect protoplanetary disks, e.g. in the Orion nebula stellar nursery? What might be the maximal pixel scale to do so; would 0.5"/pixel suffice?

The problem isn't pixel size. It's seeing. What's your typical seeing? 2 or 3 Arc Sec??

2-3 arcseconds. But that isn't the question, which is specifically without the influence of seeing.

You might be able to detect them but you won't resolve them, Just a small darkened spot.
When the start talking about radio telescopes there is always a reason-
If I did the math right, some of the bigger ones are about 1 arc-sec. If you have 4x that resolution (0.25 arc sec) then you start to discern shape. At 10x with star to see "stuff) (i.e. 0.1 arc sec),
Just my guess, I haven't tried it. Be really tough with seeing.
