I did not find plasma-workspace product, please reassign if this is not the right one.
Opening this so there will be a followup for  which was not resolved so far.

since the commit with the id 78c97fin plasma-workspace , it depends on
NetworkManagerQt and hence on Network Manager unconditionally. The use case
outlined in the commit is that the data engine tries to access wlan via network
manager to find out which hotspots are around and use that to get location
Now apart from the fact that I wouldn't want it to do that and that it couldn't
do it on my system, because it uses systemd-networkd for network configuration,
this results in a dependency on Network Manager.
I do understand that Martin when introducing this commit thought that most
systems running Plasma 5 will run Network Manager anyway, since that is a
preferred way of setting up network for many distributions. However, there are
many systems, that don't need and use Network Manager and possible don't want to
have it installed at all.
Aside from my desktop computer, examples could for example include workstations
at universities, which often have a static network setup (doesn't matter how
that is setup).
So the question is:
Could you make this feature, and therefore the dependency on Network Manager,
optional at build time?
Currently, I just comment out the geolocation dataengine in the corresponding
CMakeLists.txt and remove the dependency when building plasma-workspace, but
since I don't know about the code, I can't judge if this has any unforeseen
consequences, if a data engine is missing.
There was great effort in the past to make KDE modular, this was a positive effort which paid off (unlike gnome).
Adding network manager as mandatory dependency for core component is a step backward, there are many people out there that do not require network manager nor any other optional functionality and still wish to use KDE.
If KDE is going monolithic again (runtime/build time dependencies) or core depend on specific services without intermediates (systemd / networkmanager), it just follows the gnome steps and will not be usable but in specific environments, these who wish to have a choice go to other desktop environments.
I, for example, am a user of KDE for the last 13 years, will be sad to move away, but will if choice is taken away.
