For the record, what I was hoping/exoecting the 'in' syntax would
accomplish was eliminating the need to write stuff like the latter;
i.e. that

  mount options in (ro, atime) /dev/foo,

would be equivalent to

  mount options=ro /dev/foo,
  mount options=atime /dev/foo,

and not

  mount options=ro /dev/foo,
  mount options=rw /dev/foo,
  mount options=atime /dev/foo,
  mount options=noatime /dev/foo,

That said, I can kind of see the consistency argument, where multiple
options= entries are like multiple permission modes (r, w, m) on file
