It wouldn't surprise me if they are looking at introducing this in
Netherlands as the whole country is zoned.

The Dutch railway system over the whole country is about the same size
in terms of number of stations and permutations of routes as TfL is in
just London. Try Zoning the non-TfL bits of the UK and there will be so
many winners and losers you'd never hear the end of it.
