To enforce the licence one doesn't need any copyright (asignment) at the work at all. You just need to be appointed by (one of) the copyright holder(s) to enforce it.
This is not generally the case. If you don't own the copyright, you cannot enforce it unless: (a) you have been given a contractual right to do so *for value* and join the copyright holder as a party to the action; or (b) you are an insurer who is enforcing the right for insurance purposes. This is something that may vary between jurisdictions, but that is the basic rule in common law jurisdictions.
Scott Ritchie:
Fortunately, in order to enforce the license they don't really need rights to all of it, or even most of it - just rights to substantial portions of the useful stuff. Heck, Alexandre's contributions alone could probably be enough code to cover virtually the entire project.
This is correct - the only reason you would need to own the whole of the copyright is if you wanted to re-license in circumstances or under terms not within the existing licence.

I'm living in the EU, where the copyright is split into "usage rights" and "creator's rights" and only the usage rights are transferable. I'm not into that legal stuff too much, so I'd leave that to experts to decide on, but I'd like to see a conclusive explanation on how this will apply to all of us new and old Europeans.
The inalienable right (that is, incapable of alienation by the owner) are moral rights that are unimportant for present purposes. They include things like a right not to have derivative works involve a derogatory treatment of the prior works. These rights also exist to some extent outside of the EU due to laws implementing various copyright convention obligations.

Copyright assignment in other projects has been tricky, and it can't be done retroactively. It usually requires developers to submit paperwork - we don't really want that .... do we?
The requirements for copyright assignment will vary by jurisdiction, but in Australia and the US it must be done in writing signed by the transferor. This does *not* mean it needs to be in the form of a contract (which is the way the FSF do it).
Non-retroactivity merely means that when you assign copyrights you do not transfer the right to take action against breaches prior to the assignment (although there will be a right to take action against further activity that derives from the prior breaches). You can assign copyright at any time *after* the copyright arises.
You cannot generally assign copyright *before* the copyright arises, however, since you cannot make an assignment in law of something that does not yet exist (in Australia the Copyright Act specifically provides for assignment of future copyright where this is done by contract, but AFAIK US copyright law does not). However if you have contracted *for value* to assign a future copyright, a court will normally be willing to force assignment of that copyright if the author refuses to do so (this is where the FSF contracts come in - although there may be issues of whether there is "value" in those), and to prevent anybody else from denying that the copyright was assigned at the time it arose.
A significant gotcha here is that the copyright assignment in each country comes under the law in that country - the copyright in each country is a different legal right. Even if a document purports to assign worldwide copyrights, if it is not in the form required by the law of some countries, then the original copyright holder will retain copyright in those countries.
