There's a lot of potential value in capturing the location data where the scan was captured.
Reasonings:
simple knowledge of roughly where the scan occurred (that hill, this property, etc)
more-precise alignment of the scan data with the geography, e.g. seeing how a cave corresponds to surface-visible sinkhole
declination of magnetic north from geographic north
Capturing scan location can conveniently (with user consent) occur automatically, with the knowledge that many automatic location captures will be fundamentally inaccurate (or impossible to capture e.g. in a cave).
To combat inaccurate automatic capture, manually updating the location after capture relative to the scan data will be necessary and useful for producing the most informative scans.
It's critical that exporting a scan not require exporting the location data! Many cavers are incredibly protective of location information, especially for private or at-risk locations, but they may still want to export location-free scan data.
