But what would be the advantage of doing that? Both packages are 
available on the "official" repository for emacs packages, and can be 
installed in a matter of seconds.

Right now the purpose of each package is clear: built-in basic support, 
auctex for advanced IDE-like features, cdlatex for quick math insertion. 
(Note that cdlatex is a minor mode, and can be used to insert maths in 
any emacs buffer.)

The file tex-mode.el which implements basic support for both tex, latex 
and doctex is less than 4000 lines long. The syntax may be superficially 
different, but a lot of concepts are common between the different 
languages of the family. Plus, one gets support for tex syntax in latex 
documents for free.

AUCTeX, too, builds support for latex on top of the support for tex.
