I think at the current state it will be waste of efforts to setup a user
repository and build everything with hardening-wrapper. There has been
several internal discussion about PIE in the past and recent times, that
is definitively something that we are aware of.
In the past there has been various (performance) reasons with gcc5 that
hold up stepping further, so the decision was to not backport gcc6
patches and wait for gcc6 so arrive. Fortunately gcc6 arrived so the
topic landed again on the tables for discussion. The current state is
that we wanted to have some benchmarking with current (non-PIE) and PIE
enabled binaries to compare them and make sure it eliminated all
previous concerns.

If you want to to really help pushing this topic in an official way then
the most useful and best step you could do is helping out to do those
