Yes, but using --force-all takes away much of your control about
whether required packages are being removed, or whether other bad stuff
happens. Stuff like --force-conflicts can get you in trouble really
quickly too

What I meant is that if it is established that a non-critical package
has to be removed but is blocked by some problem, then use the minimum
force option(s) that will do the trick. This will limit the mount of
damage that can be cone

Yes, but again, the thing is that you want to keep control over what
will be forced, and therefore use dpkg --force-overwrite --force-depends
or some similar (as required) set of force options
