Ben Kietzman commented on ARROW-9867:
-------------------------------------
Note that it's possible for a FileSystemDataset to contain fragments resident
in different filesystems or even no filesystem (buffer-backed fragment), so
this helper will return a possibly empty vector of filesystems
> [C++][Dataset] FileSystemDataset should expose its filesystem
> -------------------------------------------------------------
