Contributor agreement != copyright assignment

Maybe organizations want this, but I do not. Contributor agreements still require signing; I don't like that (Michael Meeks also explains that). Remember needing to sign something to get commit access at Mozilla (for Bugzilla). I wouldn't do so anymore. Especially when you discover it is actually better not to have Bugzilla commit access (in short: very strict on what is accepted; same for committers and random people). Needing to sign is just annoying and IMO (and seeing the presentation), you should avoid such barriers.

So no doubt the intention is good, but I still think it will have a bad effect (presention explains it much better than I can).

I like the GNOME environment: Git access = commit access to everything. Getting Git access is enough of a barrier.

I believe it is better to explain that it will create a big barrier than Project Harmony. In the end, it still requires signing, no matter if stuff is standarized or not.
