Switch default for the GRASS_SKIP_MAPSET_OWNER_CHECK?

[wenzeslaus]

The Dockerfiles in the source code (the ones used to build the official images) set GRASS_SKIP_MAPSET_OWNER_CHECK=1 to "allow work with MAPSETs that are not owned by current user". Should this be the default?

The the option to disable the check was added in 737b8f3, the check itself some time before 7.0, and the variable is described in detail in the C API doc: GRASS General Library (aka GIS Library): Fundamental Database (aka Project) Access Routines, stating that:

This was added mostly for accessing VFAT/NTFS-format external drives or network shares where the ownership checks don't behave correctly. It should not be used on multi-user systems, nor set by programs.

Trying to minimize the number of variables a user needs to set up, I wonder when having the active check is actually useful.

Are you benefiting from the active mapset ownership check? Or are you disabling it with runtime GRASS_SKIP_MAPSET_OWNER_CHECK or compile time SKIP_MAPSET_OWN_CHK? Or are you in a situation when having or not having the check does not matter and fully relying on the operating system is the way to go?
