I tested that on extlib, and I'm quite scared by the result:
[EMAIL PROTECTED]:$ ls -l *deb
-rw-r--r-- 1 zack zack 297300 2007-04-09 15:27
libextlib-ocaml-dev_1.5-6_i386.deb
-rw-r--r-- 1 zack zack 529000 2007-04-09 15:34
libextlib-ocaml-dev_1.5-7_i386.deb
As expected the changelog entry for -7 is:
[EMAIL PROTECTED]:$ dpkg-parsechangelog | tail -2
* compile objects with debugging information, patch from Ivan Jager
(Closes: #415194)
Some more details:
[EMAIL PROTECTED]:$ dpkg --info *-6*.deb | grep -i size
size 297300 bytes: control archive= 4908 bytes.

[EMAIL PROTECTED]:$ dpkg --info *-7*.deb | grep -i size

1,3M debug/usr/lib/ocaml/3.09.2/extlib/
About 50% more in the size of OCaml objects, that's *a lot*. IMO this is
enough of an argument to give up the idea, and also to strip the
standard library, but maybe we should ask for the opinions of the
release managers / the cd team.
Cheers.
