dbus vs gdbus in TDE

Hi another question that popped up when working on syncevolution plugins was the future of dbus. https://www.mail-archive.com/syncevolution%40syncevolution.org/msg05071.html It looks like it is getting replaced by gdbus and I found that libraries are linked to dbus-1 for some reason I do not understand. Example ldd /opt/trinity/lib/libkaddressbook.so | grep dbus libdbus-1-tqt.so.0 => /usr/lib/libdbus-1-tqt.so.0 (0x00007fb69ebb2000) libdbus-1.so.3 => /lib/x86_64-linux-gnu/libdbus-1.so.3 (0x00007fb69d452000) ldd /opt/trinity/lib/trinity/libkaddressbookpart.so | grep dbus libdbus-1-tqt.so.0 => /usr/lib/libdbus-1-tqt.so.0 (0x00007f61da129000) libdbus-1.so.3 => /lib/x86_64-linux-gnu/libdbus-1.so.3 (0x00007f61d89c9000) What are the plans and what can we do in future? thanks and regards
