A very good question! We can be sure that many Transit points will be vague. No one wants to have the finger pointed at them, with the rules changing all the time.
I did find something on the Austrian government's website:
When entering Austria from abroad, a medical certificate or a valid negative test result in German or English language for SARS-CoV-2 must be available and presented to border authorities upon request. After entry, a quarantine of 10 days is required.. . .
People whose entry is subject to one of the following exceptions do not have to register, and quarantine is not required:
. . . Professional transfer journeys/transfer flights.
. . . Transit through Austria without a stopover, which also applies to exclusively indispensable interruptions, provided that a departure is ensured.
This isn't specific to airports, but seems it should apply, no? Wishful thinking?
