This is the best approach, but it won't go anywhere because it requires a
lot of work and not enough upside (or else it would have been done already).

People who want to ban MPL or any other library are effectively admitting
they have no skin in the game (they don't use it). We should hear from
actual users, but we won't; they don't have a problem to complain about,
because we have not broken their code yet. We should keep it that way.
