Implement a custom url scheme to import data - GPX, KML, TileJSON, MBTiles, etc

Importing data currently involves a lot of steps.  It could be greatly simplified by defining a custom URL scheme that sends the request to your app when clicked. Something like gaia-gps://www.mydomain.com/mydata.gpx.

It would be useful for GPX, KML, TileJSON, MBTiles and any other data that users can import.

I want to on board a large number of users that will be using an online data source that I'm providing. The current workflow involves a lot of decisions and navigation that will be a obstacle for a lot of people. A custom URL scheme reduces the task to a single click that everybody can get right.
