I think you shouldn't worry too much about re-coating at all.
I had something similar: residuals of hot pixels (visible on attached very-stretched image), because I was in a hurry and I used master dark from previous night, so sensor temperature did not match.
They look like this (extended) because the alignment was not ideal, and DSS stacker stacked stars, not hot pixels - so they are "smeared".
I would simply ignore details like that - adjusting dark level will take care of them/
