Here are some packages installed on my computer and (to various degrees)
important for me which depend on Qt5
1. x11-wm/lumina
An excellent desktop environment. I use it for many years.
I contacted the upstream about the possibility to port it to Qt6. They
said that before that they have to port it from qmake to cmake (work
underway), then they will consider the possibility of the Qt6 port.
2. media-sound/qmmp
An excellent misic player. The site says there is qmmp2 based on Qt6, but
I don't see in in Gentoo.
3. media-video/vlc
An excellent video played. Its GUI is Qt5 based.
4. app-text/master-pdf-editor
The only tool for editing pdf files. I have to use it every time I check
and correct proofs of my papers, i.e., rather often. There is no
replacement.
5. sci-visualization/gle
A very useful tool, its gui is Qt5 based. I use it practically every day,
it is essential for my main work. But I use the command-line tool;
personally for me, GUI is not important.
6. app-text/doxygen
GUI is Qt5 based. Personally I don't use the GUI.
7. sci-geosciences/qmapshack
The best tool to support large collections of gpx tracks. There is a
partially working Qt6 port: translations and the help system are broken in
it. Personally I can live without translations and the help system. But
stabilizing this version is out of question.
So, removing Qt5 will break computers of many users, including my
computer. In the course of many years of existence of Qt5 a large number
of useful programs have been created; not all of them have been ported to
Qt6. Are we going to throw away all this wealth?
