Could be.  Feel free to bring it up on emacs-devel.  But the size
issue of the ELisp manual is very real: it already prints as two quite
thick volumes.  So we will continue trying to keep some less important
parts of the manual be excluded from the printed version.

Why don't you use the on-line version, either Info or HTML?  The PDF
version is basically needed for printing the manual, not for reading
it on-line.
