[Interest] Impact of QtWayland licensing on applications bundling OSS Qt?

Looking at the source, I did a quick scan of the repository to see what 
was LGPL and GPL based. Your description of the situation was pretty 
spot on, Thiago, though there are two files in the client project that 
are GPL licensed. These files are new in Qt 6.3; they don't exist in any 
version of Qt prior (including 5.15) and were added in the following 
commit: d89c892

Scan results: https://gitlab.com/-/snippets/2353685

Examining the cmake config for the client project, those two shell 
integration files are included in the WaylandClient module's sources 
(lines 51 and 52). As I mentioned previously IANAL, but would these 
sources files have the impact of GPLing the QtWayland client library? 
How Qt likes to handle the "not-really-meant-for-public-use" APIs is a 
bit beyond me.
