Hmm, I am not convinced we want to come up with our own matching syntax
there.

A different approach might be to just use awk here. awk has been
invented for this kind of matching. So it might be nicer to just have a
mode where we have an output that is easily processable by awk, and then
people can do all matching with awk?

awk is pretty well known and widely spoken. And I think it is pretty
good with CSV style dumps, so maybe we should just support that nicely...
