Indeed most NOK extensions are from the Maemo/Meego days and are
(were?) used around Qt.

Currently neither extension (or any Nokia one fwiw) is used by Qt
4.8.7 or 5.8.0 itself. Perhaps the biggest Qt user - KDE does not seem
to use them either.
Disclaimer: I've only checked the latest supported binaries - KDE Apps
17.04.1 and KDE Plasma 5.10.0, I haven't gone through the dozens of
git repos.
