Thank you for asking to clarify. I agree that this bug report discussion
can be difficult to follow.

Because they aren't used.

Why aren't they used? Because it is a violation of Debian policy to
install third-party bundled libraries; instead, the libraries should
each have their own first-class Debian made from the source for that
library.

You might want to read <URL:https://bugs.debian.org/848188> describing
why the library dependency is removed from the ‘python-coverage’
package.

I agree, and this is discussed in the bug tracker for Coverage.py
<URL:https://bitbucket.org/ned/coveragepy/issues/474/>.

I don't quite understand what you're saying there. There are
incompatible libraries both claiming the “hotkeys” name, but that's
already known here.

Definitely not; bundling a third-party library, especially when that is
just a slightly modified version of an existing packaged library, is a
violation of policy and makes security updates needlessly difficult.
