Several hundred thousand mappers are now actively mapping under the new
contributor terms. Only 420 older contributors have currently explicitly
declined. At least 97.1% of nodes [2] and 96.6% of highways [2] in the
current database were created by continuing mappers. However, some of
those may have been edited later. From up-to-date figures, [3], it looks
as though 3.2M out of 120M ways are problematic in some way. That is
2.68%. It is declining. So, if we can use just one figure, I suggest we
could be at 97.32% readiness ... feel free to challenge!
