https://pubs.opengroup.org/onlinepubs/007908799/xsh/open.html doesn't
mention anything about what filesystem types back the path being opened.
It does say that O_CREAT without O_EXCL should have no effect if the
files exists.  That this particular instance is related to procfs
shouldn't make a difference, right?
