Primarily because its a port: https://www.debian.org/ports/ and
https://www.debian.org/ports/arm/ .

Other, lesser reasons include there's no documentation (follow the
links above), and using non-port procedures fails sooner than the
ports procedure:

I: Running command: debootstrap --arch armel --foreign --keyring
/usr/share/keyrings/debian-archive-keyring.gpg --variant=buildd
--exclude=debfoster unstable debian-armel http://ftp.debian.org/
I: Retrieving Release
E: Failed getting release file http://ftp.debian.org/dists/unstable/Release

I would be awesome if someone would clearly document the procedure.
