Overall, this looks excellent. Thanks for the work, @DeaMariaLeon! I've left some minor comments.

[hameerabbasi]

Thanks! This should auto-merge when CI passes.

I tried to "acknowledge the performance issues" on codspeed, but I'm lacking the rights to do it.
I'm talking about the report's note above:

⚠️ Please fix the performance issues or acknowledge them on CodSpeed.

It's just that the benchmark changed name, and codspeed "thinks" that it's missing. I think we need to fix this in order to merge the PR, as codspeed will block. @hameerabbasi
