An headless deamon can be anything with any use cases. One use case that
I came with, where the dconf model did not work was package managers.

Not, GLib networking proxy support was first implemented transparently.
Application now has required API to prevent the proxy resolver to be
called automatically. They can also pick and setup a configuration they
want, regardless of what the system settings are, and regardless of
where the settings are from. Though not used at the moment, an example
use case is S5B, a proxies file transfer API in XMPP that uses socks
protocol for handsake. Current API has now enough flexibility to be used
to handle that.

It's a wired concept, which got added NM "recently". The idea is to have
different settings for different wired network, but unlike WIFI, there
is no natural way to identify it. So you can configure multiple
profiles, and user can choose the profile manually. More advance
implementation can add up heuristic, like the gateway mac address, the
subnet, etc. to automatically pick the profile.

Proxy configuration could also be attached to VPN settings, as being on
certain VPN may require specific proxy etc.

I have never programmed it myself, though it's supported in
nm-connection-editor. Basically you can have multiple settings for the
same wired network. For work laptop, it's often (but not limited to) a
home vs office configuration.
