If it's not automated, it requires to much additional effort. It is worth to do for really big projects which can't be developed without community effort, but not for smaller ones which almost work and only require small fixes from time to time. Also on such projects people don't know each other, and don't know how much everyone have contributed, so there's no way to have meaningful discussion and consensus.
