I just discovered that Gantt has been proposed as a potential subject of 
interest for GSoC. While I do understand the opportunity for people 
working on Gantt, I don't think, as Russell stated, that Gantt is mature 
enough for helping newcomers to deliver cool features within the given 

IMHO, Gantt should be removed from this wikipage [1], and be replaced by 
Nova proposal for Filters/Weights improvements. The Solver Scheduler 
recently received NACK for a FFE (Feature Freeze Exception) so that 
means that new patches wouldn't be merged until Juno (12th May), so I 
guess the problem would be the same too.

Anyway, people interested in working on the Scheduler should attend 
weekly meetings on Tuesdays, for at least synchronization within the team.

My 2cts,
