The solver does not distinguish between manually and automatically
installed packages. I'm trying to find the time to write a new solver
from scratch because essentially if you dare touch that it's going
to explode in other bits, but I can't make any promises. You can
track work in
https://salsa.debian.org/apt-team/solver3
Like consider you installed foo manually and it got renamed bar, you
want to remove foo and install bar when you upgrade. But if you try to
teach that to apt's existing solver it will go fail in all sorts of
hilarious places because it's 30 year spaghetti code that's not
capable of running with that many restrictions.
