I was surprised that the authors of the paper seemed unaware of the use of meteoric iron in the Indonesian culture.

I don't think it is so much a matter of being unaware of meteoric use in Indonesia as much as that their focus is more on the use of that material by ancient peoples.
The remarkable thing about this dagger is that it was created at least a century before the acknowledged start of the Iron Age and many centuries before edged weapons were commonly made of iron.
