When using a backports package, the breakage is confined to that
package. When pulling in newer libs aswell, it might be that some
totally unrelated part of the system, e.g. another service on that host,
breaks because of a change of behaviour in that library that is not
triggered by the application for which I upgraded it.

It's a matter of reducing risk: if code works, do not change it unless
necessary. If I can upgrade one application and keep other existing code
in place, I prefer that of changing it just for the heck of it.

An example: I run a stable system with apache and php from stable. I
want to run some web application only in testing, which requires a newer
PHP version. The version of the webapp in backports is modified to work
with stable PHP, so that I can keep my working apache+php installation
and still use the newer web application. Getting the version from
testing directly requires also upgrading PHP, potentially breaking other
web scripts that users of my system have installed.
