Could this be implemented simply as QEMU upstream tracing + trace parsing scripts?

Quick naive architecture question.

Now that QEMU 2.12 has record and replay "working" on master https://github.com/qemu/qemu/blob/v2.12.0/docs/replay.txt , can't you just use upstream all the tracing that you need for this project using https://github.com/qemu/qemu/blob/v2.12.0/docs/devel/tracing.txt , and then keep just trace parsing scripts on this repo?

If possible, this could make things more manageable.

Hmmm, memory tracing seems impossible due to QEMU optimizations:
