Most distributions also don't allow to 'customize' any of the following:
- compiler used for building the distribution,
- libc implementation,
- C++ standard library implementation,
- coreutils implementation,
- system shell,
- kernel (e.g., using Hurd),
- PAM or equivalent,
- util-linux,
- package manager,
and so on. systemd is just one more thing in that looong, looong list.
