Hi, I would say, this is not really critical. As far as I understand, the emacs compat file is a policy requirement, which is not used currently.
The fix is easy, just include a file <package>.emacsen-compat with content 0 in the debian directory, see for instance https://alioth.debian.org/scm/viewvc.php/emacs-goodies-el/debian/debian-el.emacsen-compat?root=pkg-goodies-el&view=log and /usr/lib/emacsen-common/packages/compat in your local debian installation.
