Doesn't JWST have to account for its own orbit around L2 and stellar parallax (depending on distance)? I assumed it would have to have some tracking.

True, but those are minute parallax changes, not "entire view angle in 8 seconds".

I have no idea, it just made sense in my head that when you're cropping such a small portion of the picture, any movement would be visible and would probably fuck up data. In my mind the lens(es?) are in constant motion while in use. Itty bitty tiny little movement, but movement.

I mean, there's probably a good reason the JWST costs billion and I can get a camera for 12 bucks. Your questions are probably one of the many reasons.
