Hi Adhemerval,

Thanks for your v2 review and the proposed solution.

I have read your suggestion and understand the rationale. I do have some reservations about it, but I thought it would be premature to propose my own idea without testing it first. So in v3 RFC, I implemented a reference version and did some preliminary validation. My goal was to explore the feasibility through an actual implementation, though I realize it may not be fully mature yet.

I should have replied under the v2 thread when posting v3 RFC to explain my reasoning, but it was delayed—apologies. I will very soon post a comment under your v2 reply with more detailed explanation.

I’ll also test your proposed solution and compare it with my current implementation to see which approach works better. Happy to continue discussing improvements.
