You don't really need copyright assignment (IE you can go along with
just licenses) unless you plan on suing people over your documentation,
which seems even less likely than suing someone over your code.
I don't follow. The issue is that somebody claims that the FSF documentation
infringes on their copyright and claims that the disclaimers on the Wiki do
not constitute a contract or license. It would be very embarassing to the
FSF to be found guilty of copyright infringement and it doesn't matter
whether it's in code or documentation.
Forcing people to write more documentation will only work if it's not
really extra work for them.
Again, I don't follow. Writing documentation certainly is "extra work".
Indeed it's often much more work than writing the code. But it's a very
critical part of software development and if people aren't willing to do it,
their contribution isn't very valuable.
