Yes - POSIX requires this:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/mkdir.html

-p
    Create any missing intermediate pathname components.

    For each dir operand that does not name an existing directory,
effects equivalent to those caused by the following command shall occur:

    mkdir -p -m $(umask -S),u+wx $(dirname dir) &&
    mkdir [-m mode] dir

    where the -m mode option represents that option supplied to the
original invocation of mkdir, if any.

Since POSIX requires the existing behavior, there's unfortunately no
room for improvement, and I'm closing this as not a bug in coreutils.
