Sorry, but that's just nonsense.

We don't have a "weird" code base. Marble mostly consists of a library that can be \
compiled with Qt4 as well as Qt5. This isn't particularly unusual since Qt5 isn't too \
different from Qt4 in terms of APIs and since Marble relies on Qt's core APIs which \
haven't changed much.

A KF5 port can be done and would certainly be an easy task for somebody with KF5 \
experience: You basically take the existing "marble-kde" folder which consists of \
about 2500 loc:

tackat@tackat-ThinkPad-T500:~/marble/sources/src/apps/marble-kde$ wc -l kdemain.cpp 
408 kdemain.cpp
tackat@tackat-ThinkPad-T500:~/marble/sources/src/apps/marble-kde$ wc -l \
KdeMainWindow.cpp  190 KdeMainWindow.cpp
tackat@tackat-ThinkPad-T500:~/marble/sources/src/apps/marble-kde$ wc -l \
marble_part.cpp  1947 marble_part.cpp

I guess the best approach is to copy that folder over to marble-kf5 and do the \
porting. The code in these 2500 lines mostly deals with KPart and KConfig. For \
classes where KDE classes have disappeared code can be borrowed from the \
source/src/apps/marble-qt directory which contains a Qt based feature-compatible \
client.

Best Regards,
Torsten
