.DS_Store, .fseventsd, .Spotlight-V100, .Trashes, and ._this and ._that
These can all die in a fire too, as far as I am concerned. macOS loves to treat the user's filesystem as its own personal garbage dump.
OTOH, If you want the information contained in those files, where else would you save it?
thumbs.db and those weird MS alternative stream files for recording origination.
filesystem attributes are for decorating files with meaning. Anything else that attempts to use filesystems in "interesting" ways is silly.
Apple and MS really ought to consider why they do this sort of fragile, idiosyncratic nonsense.
