Sure. Though I wouldn't categorise the USA (and to some extent Canada and UK) finally getting on board the same metric bus as the rest of the planet as entirely "unnecessary".
I don't understand why it's necessary to implement methods in your own situation just because someone else is using them in theirs. That seems to be a cargo-cult mentality. If there's no endogenous case for using the metric system, why do so?
By the same reasoning, you could argue that people should all adopt e.g. Esperanto in place of their own languages for use in all circumstances without distinction.
