Almost certainly isn't... clearly it has occurred to Google that their 3D dataset would be useful outside of their application. If Google wanted to provide this capability they would have. Sketchup would have been a logical connection but they chose to only allow for 2D import. More recently Google Studio has provided great access for this type of use case (via a different methodolody) Google again chose not to allow for export of the 3D data.
It is unlikely they will go after a user like Herbo. A software developer enabling this type of use to be scaled up might raise eyebrows.
Yes, you are probably right!
