Ouch, that does sound like a painful cycle. It happens, and no one tests as much as they'd like to.
> Portability of the data.
I hear your concern here. The replay data and session data is also saved to disk, so you can save this somewhere. Of course that still leaves the risk of the record & replay tech. I think open sourcing this would solve the portability issue here, and it's something we're actively talking about but haven't reached a conclusion on yet. Anecdotes and examples like this though are incredibly helpful in helping us make that decision.
Thank you for the feedback!
