You are right.
However; the KDE agreement explicitly states that Qt add-ons must be
available under GPLv3.
So I am wondering if there could be issues with licensing under LGPLv3 but
not under GPLv3, even if for KDE it is equivalent.

All recent and upcoming modules, except Qt 3D, are GPLv3, but not GPLv2.
The reason I started this thread is that I needed an http server for a Qt
project under GPLv2,
I started to play with the QHttpServer (still work in progress, but working
nice) until I realized
I would not be able to use it because it is GPLv3 only.
