The Debian package installation is hardcoded to install files under /opt. As a result you have a package that is scattered over the user system under /usr and /opt (as you naturally try to integrate it properly with the system).
This causes a number of issues, starting from the weird dance with update-alternatives to place the binary into the PATH and other issues with mounts and permissions.
Arguably, it's also not the best practice to put package manager managed stuff under /opt at all (I understand this might be common).

At least, I think it would be nice to allow the user to configure this behavior.
If this is something you'd be willing to accept - I might looks into it.
In this case, most of the package core files should go into /usr/lib/<package-name> (instead of /opt/<package-name>) with other files installed under respective directories.
