This is just one of the many possible usages.

Thius has nothing to do with exporting an environment.  The export
operation and the writing to the file system are two separate steps.
If a file system driver contains write support or not depends on the
file system code.  For the environment it does not matter.  If we have
write support, we just use it.

As mentioned, this is but one usage.

I think that "env import" / "env export" should be kept symmetric.
