True but ... pinning actually works OK for most packages.

I wonder how this system address package name changes.  (e.g. coreutils)

If you have *WORKING* unstable system, I doubts why bother doing
downgrade.  For the broken system, fancy downgrade through
install-and-switch may not be the option.  (Besides, if it is working,
just run many chroot to test many environment for fun)

As for real life downgrade, I still think pinning is useful and works
mostly with minimum manual work.  See example of real trial by the user:
