Looks reasonable for me, if it can arrive at a consensus within FreeBSD
KDE team. In the meantime, I'll lock AppStream pkgs.

Another option would be, if possible, FLAVOUR'rize or OPTION'nify
devel/appstream-qt for Qt5 and Qt6, defaulted to Qt5 for now.

Currently, Qt5 components on FreeBSD are depending upon patches from
KDE, starting from commit 6b3bece75ad5a3d03e2751e5cdf78ae8aeb0abf9 [2].

So, IMHO, Qt consumers which affect KDE component would basically need
to default to Qt5. Of course, ports that do not affect (impact) with
KDE components are free to choose Qt6. :-)
