That would be a very narrow and strict interruption of cc-by-sa,
especially since the assumption is a derivative is required by the
user to generate any changes made when the source of their changes
would matter just as much.

For example if they are using GPS data all they would use existing
data for is to work out what doesn't need to be done.

Same would go for the Canadian mass import currently occurring,same
goes for other data imports such as OS.

The only time it would matter is for things like extrapolation the
position of streets based on the location of existing streets.
