Lots of good discussion here. We seem to be split into two camps:
1. Those who think an airport specific, verifiable, subset of of tags
would be best
2. Those who think a general importance tag with numeric values would be
best
Both have benefits and drawbacks in my mind. Either way

But what you can do is compare it to the surrounding / context /
nationwide / worldwide. It's like the highway key for tertiary,
secondary, primary.

In terms of airports, you really can only compare them on a world wide
basis, it doesn't matter where a small airp

Great! I like it.

So a trunk road crosses a primary road, but you're not allowed to turn
at the crossing. Instead you have to turn before or after and loop
around to get from one to the other. If this connecting status is the
sole reason through traffic would have for using the road, how should
it be tagged? trunk?

That's not what highway classification is for:
