My argument is that it may well be less effort to continue
supporting XP and Vista on mozilla-central for another two years
(followed by ESR for a bit) than to support ESR52 for three years.

So if we're actually talking about possibly maintaining ESR52 for
three years, I think we'd be better off not doing this, and
continuing to support XP and Vista in our non-ESR releases.

If we're willing to make a firmer commitment to ending support, I
think the plan becomes more reasonable.
