If you just want your application to run in a Wayland session, you need the
client library and plugin only.

This is good to know. I don't know what I was looking at last week, but I could have sworn when I was going through the code last week I saw some disconnects between the license headings in the qt/qtwayland repo. Good reason to not look at code late at night! Looking at it again today things seem to line up with your information. Is this explicitly documented anywhere outside of the code headings? From what I could find in the Qt docs the only license mentions are around the compositor and integration plugin:

=== https://doc.qt.io/qt-6/qtwaylandcompositor-index.html
Qt Wayland Compositor and the Qt Wayland integration plugin are available under commercial licenses from The Qt Company.

In addition, Qt Wayland Compositor is available under the GNU General Public License, version 3, while the Qt Wayland integration plugin is available under the GNU General Public License, version 3 or the GNU General Public License, version 2.

In terms of bundling with the rest of the Qt framework, you're saying just the following artifacts from a build are needed? I don't know if any other objects or resources from the QtWayland package are necessary.

- libqwayland-{egl,generic}.so
- libqwayland-xcomposite-{egl,glx}.so (optional for Qt5?)
- libQt{5,6}WaylandClient.so.{5,6} (linked by the above objects)
