The package substitution isn't something we can do at the package level,
because conflicting on that package would prevent coinstallation of
RT and many other packages which depend on JSON::XS.

However it was pointed out to me that we could force the version to
use via an environment variable:

https://sources.debian.org/src/libjson-perl/2.97001-1/lib/JSON.pm/#L488

This should be possible to ship in default configurations: I'll look at 
that when I have a moment.

Best,
Dominic.
