Well, every pacakge that does
install -o root ....
(and there are quite a few of those) will fail.

This will of cource only work if all files are owned by root in
the package. Otherwise, the debian/rules file will have to do
something like chown, and that will faile (like all games).

This means changing all those packages.

Well, actaully, fakeroot is rather similar to what you are suggesting:
- by having the LD_PRELOAD=libfakeroot, I in effect modify the
build process, and I _am_ listing the correct ownerships in
something, like you are suggesting (though I don't do it in
a file, but in a binary tree).
- by having the LD_PRELOAD=libfakeroot, I in effect modify
the "dpkg --build", and it now reads that binary tree with
the ownership information, and puts it in the tarfile (inside
the .deb file).
So, basically I'm doing excactly what you intended, only without
modifying one single debian/rules file!
