Personally, I've come to the conclusion that CLA are pretty much bullshit.
We have other tools for provenance, with the Sign-off trailer in commit messages. Maintainers need to pay attention either way, and in that respect, the Sign-off trailers in front of you are just as easy to deal with as any commit author.
As for increasing the freedom of the maintainers, the creates a power imbalance which isn't very palatable when you thinkg about it.
