Sure. I'm less focused on the content of the file and more the steps
the user might have taken to resolve the conflict.

I'm trying to mimic that a user might realize that a filename might
need to be renamed (say, because a naming convention changed that is
causing the conflict) and I don't expect users to use 'git mv' to do
this action.

'git mv' had not occurred to me as a thing to do in this case. I'm
focused on ensuring that 'git add' works as expected to update the
index in response to filesystem changes.

--force is focused on _ignored_ files. I imagine that it could be
repurposed to allow entries outside of the sparse-checkout definition,
but we would want to be careful for users who are adding the entire
directory, not just the individual files, as they might _also_ get any
ignored files that exist in that directory. That might justify creating
a new option instead.

Further, the error message reported when adding something outside of
the sparse cone should probably mention whatever option exists as a
way for users to bypass this limitation. I'll collect my thoughts (in
response to your detailed thoughts shared on my cover letter) and
start a new thread about hardening this behavior. I've got an internal
ticket tracking this, and I want to wrap my head around all of the
interesting commands (add, mv, rm, update-index?) and create a full
recommendation to bring as an RFC.

Of course, if someone else wants to create this clear vision in the
meantime I will not complain.

Thanks,
-Stolee
