But I am not sure it would be productive for us to get working code out and loose the functionality or delay its submission. As Record/Replay is pretty much functional with this set of patches I am hoping that we can do a complete rework if required later on.

If there is something broken related to the submissions, the common
practise could be one of them below:
1. Fix them first,
2. Document the existing limitations/problems or write a test case to
kfail it. In this way, people are aware of this.
3. Continue the submission and revisit the problems later.
Personally, I choose one of them, depending on the complexity of fixing
the existing problems. This patch series is a large one, and based on
some existing code. I would like to fix existing problems first, before
doing something new, if it doesn't take much time on fixing existing
problems. These patches are preparatory, and usually simple. so they
have more chances to be reviewed in a timely manner. These preparatory
patches set up a context for your large patch series, and the context is
helpful to understanding your patch series. As a result, the review
process may be shortened.
I don't want you to fix existing problems first, or take other actions.
Just let you know something submitters can do to help maintainers to
approve patches.
