Yes, the discussions and proposals are endless for this. Suggestions
are usually that you should deduct the importance by analyzing the map
dat (e.g. surface of the runway, length of the runway) and combine OSM
data with external sources (numbers of starts/landings a year, number
of passengers a year, freight volumes, ...).

Personally I think that to get a rough estimate it is sufficient to
tag the most important ones with

aeroway=airport

this renders nicely and is suitable IMHO, even if it is not the
ultimate level of detail.
