It strikes me that if I want to display a marker at an address and
find its location by geocoding, I have a location. If that location
differs in the new data, and it's now wrong, I can choose whether to
use the new place or the location I know to be correct.

With "pre-found" points, we may well already know they are accurate.
Why risk getting it wrong?

This doesn't apply to new addresses, where we have no choice but to
use the new data. But if we're finding known addresses in advance,
like we're supposed to, we may well wish to correct inaccurate
geocodes. Who owns that corrected data? It's entirely possible that
the location we correct the geocode to exactly matches the previous
provider's data, isn't it?
