Not really. What I want is:
* no removals = good
* any number of removals = bad
Minimizing removals seems to be the best choice to do that. I would
prefer something like "removals ? 10000 : 0", but that's not possible.
Now, the "removals" solution cost guarantees that the first solution
doesn't contain any removal. So, that's OK. I can do a clean upgrade
first (without removals at all), then inspect what to do about the
removals. Without the "removals" solution cost, this is not possible.
