No, you missed the point. Entirely. The point is distribution rules
apply to re-packaging made for distributions. Not to upstream
packages. So, basically, Xenomai upstream package does not care
about any distribution rules, and the job of the Debian maintainer
is to massage Xenomai installation so that it fits Debian rules.
Look for instance at how the libcurl3 packages are made. libcurl3 can
use openssl, gnutls or nss as providing TLS, but was not meant to
run the three at a time. Debian wants to be able to install the
three version, so what does the Debian rules does ? They manage to do
it.
Putting things into several directories was just one proposed
solution, but it is not by any mean the only one.
