If your concern is namespace clash, then I don't know if that is the
case - if it is then those packages will need to conflict against each
others, I guess. Even then I believe it is still beneficial for our
users to be able to choose between
least-diskspace-cover-all-requiring-advanced-OpenType- support and
least-diskspace-cover-only-single-region-working-with- simpler-programs
packages, and I see no other ways to cover both those scenarios.
