AFAIK, that option is specific to HFS+ with compression, preserving an associated extended attribute; but it preserves it even if the receiving end doesn't know what to do with it properly (whatever that is); so I'd want the destination system to be as new or newer, to be reasonably sure it could. Not sure whether it's of any use with APFS.
