Not sure what you are trying to show with that grep ...

# strace mount |& grep mounts
# strace mount |& grep mtab
open("/etc/mtab", O_RDONLY)             = 3

mount does read /etc/mtab for displaying the mounts. It only looks at
/proc/mounts if /etc/mtab can't be read. Or at least, that is what the
version(s) I have does. I would say that the common setup is to have a
readable mtab.
