Release Team, I noticed today while reading https://bugs.debian.org/1107304 that python3.13 was not included in the toolchain packages list [1]. My reading of the list is that it was intended to be there. If it had been on the list, the last version that would have been allowed into Testing without an explicit unblock request would have been 3.13.2-3. There have been five python3.13 uploads to unstable after that and there hasn't been one unblock request yet. It is at least clearly a key package so it will need an unblock request for any newer version to reach trixie.
Similar situation for python3-defaults and now python3-stdlib-extensions. Thank you, Jeremy Bícha
