My current thinking is: * add the pre-freeze ABI flag proposed in PEP 605 * as long as that is set, both the full ABI and any stable ABI additions since the last stable release are still mutable * we emit a compile warning if the target stable ABI is set to the in-development pre-freeze one * clear the pre-freeze flag for rc1 That way folks will be able to freely build and publish binaries prior to rc1, as long as they're targeting the full ABI or an older version of the stable ABI.
