Apache's agreement is a CLA but appears (to my eyes at least) redundant as it delivers no more than the Apache license itself. As such I would regard it as unhelpful since it legitimises the use of CLAs without delivering a significant community benefit.

Ok, so if I understand this correctly, it confuses the issue (it certainly confused me!), which is harmful in a broader sense, but if I sign it, it shouldn't be harmful to myself personally.
At least, it is no worse than putting out my contributions under the non-copyleft, BSD-style Apache 2.0 license...
