Would something like org.eclipse.ajdt.aspectpath be on for every dependency? I.e. in the existing WTP support, everything is exported in the component file and thus in WTP 2, every single dep would have the org.eclipse.jst.component.dependency attribute... that may not make sense in some projects, but it is compatible with the older WTP support.
So what I'm asking is... is that good enough? If so, I think maven-eclipse-plugin can handle it fairly easily. If it is not, it may be trickier... As of right now, maven doesn't have a way I know of to parameterize the deps to indicate which do/do not need aspectpath. So, you'd have to have a plugin config for maven-eclipse-plugin that duplicated every single dep to add that config.
