I'm a regular multi-screen user and didn't encounter problems.

Can you elaborate some more? I don't really understand the difference
between what you expect and what you experience.

Can you describe an exact example of what you do, what you expect and
what actually happens?

The canvas positions are saved with the patch and I haven't experienced
any inconsistencies with that. But I imagine you can trick it into
doing funny things when you save a position that is non-existent when
you open the patch again. Let's say you have the second screen right of
the first screen, then any canvas put there will have position values
bigger than your first screen. I actually don't know what happens when
you open that patch with a single-screen desktop. My window manager
tries to place it in the nearest free screen space from top left.
