Code added to Emacs has to follow certain rules about license and
quality. Reasons why the code you ask for is not in Emacs might be several, but
I would tip probably because the author(s) didn't signed the FSF copyright
assigment, or they simply didn't cared themselves to submit their packages into
Emacs.

Also even if you think a package is very useful, it might not be useful to
everyone. I would prefer to even refactor some of built-in packages into gnu
elpa instead of having them all in Emacs.
