Description:

We depend on this package for ros-melodic-rviz, and we ran into an issue with how sip bindings are located. You can see the diagnosis here:
- https://github.com/ros-melodic-arch/ros-melodic-rviz/issues/9#issuecomment-570678436

The key issue boils down to python2-pyqt5 putting sip bindings in /usr/share/sip/PyQt5 (which is a backup location checked by ROS sip_configure.py utility[1]), but this package has shifted all of those bindings to /usr/lib/python3.8/site-packages/PyQt5/bindings.

When I search this directory, I *only* get hits for arch linux. I'm trying to diagnose is whether or not this is a canonical changes (sip or python2 -> python3 related), or whether something is awry on arch's packaging. Here's the upstream bug report with ros-melodic-py-qt-binding, which owns sip_configure.py.

In short... what was the motivation in moving from /usr/share/sip/PyQt5 to /usr/lib/python3.8/site-packages/PyQt5/bindings?
