[Dev] Tizen:* - is X11 still needed ?

Dear all,

Why don't we continue a discussion on this topic? 

We added X11 into Common project since other profiles such as Mobile, Wearable and TV used X11 and it was huge work to change X11 to wayland in these profiles. 
But, as of now, in all the profiles (Mobile/TV/Wearable/IVI), X11 is replaced by wayland. 

Hence, I think that it's time to start removing X11 from Common. 

Actually, X11 repositories causes a lot of load to Tizen OBS system since we have 4 repositories in Common project. 

So, let's start remove X11 from Common as Dominig suggested. 

What do you think?

if only one profile is using it it should go.
X11 slow down all he build process and requires more work on each packages which depend (directly or indirectly) of a UX.

My proposition would be  remove it from Common after the next quarterly release.
