At boot, before the first mount command executes, there may be _no_
writable directory and there may be none for a while, and you have the
problem of having an existing non-empty /etc/mtab (or equivalent) from a
non-clean shutdown which you would have to erase before the first mount is
done (adding another funky option to mount). Unless you make some kind of
ramdisk compulsory, which might not be bad idea after all with current
memory sizes.
