That's how I thought it would be. Assuming that everything is
configured the right way I should have the same packages installed no
matter what system I come from.

I can imagine how often it happens in the alpha stage that packages
are not (yet) configured right or changes made in different packages
at the same time effect each other. But that's why alphas are not
recommended as production systems. I experienced several updates in
the last few weeks after which my system would not boot correctly. I
had to fix it with another update a day later from the recovery

I agree (not only) with your 3rd point. I actually use my test
installation for all kinds of tests. I test programs and
configurations on it before I transfer them to my production system.
That's why I have a test installation. If I break something I can
still work with the other one. My production system gets upgraded to
the next version when it is officially released.
