Not by name, no.  But this is in the GNU Coding Statndards:

       Generally, stick to the widely-supported (usually POSIX-specified)
    options and features of these programs.  For example, don't use `mkdir
    -p', convenient as it may be, because a few systems don't support it at
    all and with others, it is not safe for parallel execution.

If this is no longer a consideration, perhaps we should ask Richard to
amend standards.texi.
