I don't think this functionality belongs in dash. For example, I
find that the "sleep" command in

is better written (more portably and more intuitively) as
sleep $(awk 'BEGIN {srand(); printf "%d\n", rand()*327}')
or
awk 'BEGIN { srand(); system("sleep " int(rand() * 327)) }'
even though this is a little longer.
On the other hand, I would definitely like a way for users to be able
to easily choose a different shell to be used by cron, so they would
be less at the mercy of the cruel sysadmin. What do you think?
Thanks for writing,
Jonathan
