No.

I expect the targets of symbolic links to move out from under them,
unless someone (like /dev/MAKEDEV) accepts responsibility for
keeping them up to date, form this day forward, for all eternity.

I expect /dev/std* to eventually be recognized as "not useful" and
find its butt deprecated in favor of "/dev/fd{0-2}".
