Comment (by migan10):

 It looks like you can approximate the same behavior of -map_metadata -1
 with "-map_metadata:s -1 -map_metadata:g -1"

 It appears "-map_chapters -1" still works, but is equal to
 "-map_metadata:c -1"

 It could be nice to keep -map_metadata -1 functional as a similar
 shortcut. I don't know how widely it is used but I've sure used it a lot
 over the years and in lots of scripts.
