Python 2 is obsolete. It won't have upstream support anymore when bullseye is released, which means that Debian has to do all the maintenance by themselves. Even if there are no updates, that still means fixing security vulnerabilities and keeping it compatible with changes in the environment (i.e. new packaging policy, new compilers, new hardening features, etc.). There's nothing to gain but work by keeping it.
