I don't think it needs to.  There aren't many people using sparse
checkout even these days, and I think they'd generally be happy about
the change.

But if we want to be conservative until some later point (like 2.1),
perhaps --sparse should be named something like --no-widen?  That
way, I can do

        git checkout --no-widen -- .

to make the worktree match the index, respecting the sparse checkout.
And I can do

        git checkout --widen -- .

to change the sparse checkout pattern.  Meanwhile the confusing
command

        git checkout -- .

would be ill-defined for sparse checkouts --- in past git versions,
if I understand you correctly it acted like --widen, while in some
unspecified future version it may change to mean --no-widen.  No
need for warnings because I doubt anyone is relying on either
behavior.

Would that work?
