The libfoo.install file can do anything too. It's an executable, which
are turing complete.

But the debian/rules file makes it clear that there is something more
than copying going on. It points a big fat arrow at the
debian/libfoo.my-install-script.
With the automatic execution feauture you never know if there is magic
going on under the hood or not unless you carefully check every single
files permissions.
I'm not objecting to the magic part, I'm objecting to the black-box
part.

Note: With a debian.tar file you don't need the chmod I think. So
debian/rules would give you no indication that there is a black-box
thing happening via dh_install.

Let there be light.
A lot of cases will also be like
override_dh_auto_install:
sed 's/@DEB_HOST_MULTIARCH@/$(DEB_HOST_MULTIARCH)/g' <
debian/libfoo.install.in > debian/libfoo.install
dh_install
Something I would find more readable than libfoo.install being a executable.
