     • is_terrain_follow
     • outline_no_fly_zones

Minor comment: to save listing this huge list of variables to inject, could the ones from project_metadata be inserted simply using **project_metadata?

They will be used as keyword args, so this will work where the variable names match.

It would also make the code more resilient to change / breakage if variables change in future.
