Sure. My understanding of the process we'd like to follow on this sort
of thing is:

1. make proposal, test for unseen negative effects or basic rejections
2. code performance prototype
3. assemble performance evidence
4. debate utility
5. complete coding
6. further review

Step 3 is always there for performance work, so even if you don't
mention it, I'll assume everybody wants to see that as soon as possible
before we progress.
