All reports of excessive-priority-for-library-package for the archive. The extended description of this tag is:
The given package appears to be a library package, but it has "Priority" of "required", "important", or "standard".
In general, a library package should only get pulled in on a system because some other package depends on it; no library package needs installation on a system where nothing uses it.
Please update debian/control and downgrade the severity to, for example, Priority: optional.
