Absolutely. I think it's important to have clear definitions like "importance 3 is given to airports with X runways" *within* geographic regions (countries?), but not *across* them. This can be managed effectively through wiki pages for each country, describing the local rules, like http://wiki.openstreetmap.org/wiki/Australian_Tagging_Guidelines Then, the only coordination required across countries is that they all use "importance=3" to mean "an airport important at a regional level, but not one of the most important airports for the country", or whatever.
