This might rule out scrutineering in town for next year.
I can see them do scrutineering for the test day on Friday/Saturday (or Thursday/Friday) at the track (as always with test day), and a second scrutineering for the race on Monday afternoon/Tuesday also at the track as they did this year.  Was way faster than the usual 'show' in town, and also easy to organise for media to take the team shots on the track itself.

I've got a feeling that the first half of 2021 might be very similar to 2020 with very limited access to races for spectators and media.   
Kristof i think you’ve got that just about right.
