The Steering Council accepts PEP 669 (Low Impact Monitoring for CPython).
We’d like to point out that, as with any PEP, if the initial implementation requires design changes, they need to be re-approved and noted in the PEP (see PEP 1).
Please just ping a SC member on the pull request if/when you change the PEP.
To be clear, we expect that all claims in the PEP will hold, and that the PEP will mention all known cases where the implementation degrades performance.
If the changes are unacceptable, the SC may still reject the PEP and ask for reverting the change.
(You could say the PEP is “provisionally accepted, pending the implementation” – except it’s how PEP acceptance works in general. In this case, the SC does still have some reservations, but a successful implementation would be the best way to resolve them.)
— Petr, on behalf of the SC
