We are considering porting our abstract GUI class from KADAS Albireo to 
QGIS 3.0, basically what was done here [1][2]. Summary is that qgisapp 
contains all functionalities which are gui-logic independent and 
qgsclassicapp contains the logic tying functionalities to the gui 

The advantages of this are, besides better code separation (which IMO 
qgisapp could benefit from since it's become a bit of a dumping ground), 
that it easier for people to write custom guis for QGIS (i.e. very 
application specific GUIs exposing only certain functionalities etc) 
while sharing the codebase with upstream.

QGIS 3.0 would be a good moment to perform such refactoring. So I'd like 
to hear a short feedback whether people would welcome such a change in 
principle before moving on to drafting a QEP.
