I obviously agree, but there is a difference between releasing a tech 
preview or a real release, i.e. something that we officially consider 
stable (but not perfect).

So, IIUC, the idea is to create an official release to get more testers 
? I'm a bit afraid that if we create an official release and many people 
hit upon errors that we will actually scare away potential users...

But all depends on the actual current usability for a normal user (i.e. 
someone relying on the GUI).

I'm sorry, I have been fairly absent from grass-dev in the last months, 
and the situation will not get much better in the near future, and so I 
don't want to block if others are for releasing quickly. Also, I'm not 
aware of the testing efforts that have already happened (except for 
Mundialis). Are the automatic tests run systematically in a Python 3 
environment ?
