Test suites or manual testing mostly.

Because we don't want to patch all copies of a library for (security)
bugs, using embedded copies should not be done in Debian. Stripping the
embedded copy from the source is optional, so the presence of the code
does not imply that its used for the build.

Other reasons to embed code copies is to ease their build and deployment
on Windows, or to not need to a separate action to download the dependency.

As the maintainer of the proj package in Debian I say that anyone using
an embedded copy of PROJ.4 instead of building with the proj package
should be taken behind the barn and shot.

There is popcon.debian.org to show how many systems (with popcon
reporting explicitly enabled) have the package installed and actually
user it (vote).
