Whether you like it or not, don't people's automation use tons of
invocations of "git merge", "git checkout", etc.? You'd be breaking
them by such a change. Other than that, if we never had Git before
and do not have to worry about existing users, I'd think it would be
a lot closer to the ideal than today's system if "checkout <tree>
foo.o" rejected overwriting "foo.o" that is not tracked in the
current index but matches an ignore pattern, and required a
"--force" option to overwrite it.
A user, during a conflict resolution, may say "I want this 'git
checkout foo/' to ignore conflicted paths in that directory, so I
would give "--force" option to it, but now "--force" also implies
that I am willing to clobber ignored paths, which means I cannot use
it".
I would think that a proper automation needs per-path hint from the
user and/or the project, not just a single-size-fits-all --force
option, and "unlike all the *.o ignored files that are expendable,
this vendor-supplied-object.o is not" is one way to give such a
per-path hint.

At that low level, I suspect that a single size fits all "--force"
would work even less well.
