Sounds good to me, it seems like we have consensus--is there anyone
against it?

It sounds like we're going to have to make some serious changes of the
documentation--I think this is likely to be a good thing. We don't want to
make a huge curve for upgrading, but it would be nice to make it obvious
that there are changes people should consider.

I think we want to stay away from this. As it stands, allow_in_form lets
you shoot yourself in your foot. So providing some level of protection
against typos is IMHO a good thing. (OK, so it only means that you
probably *knew* that you were going to shoot yourself in your foot.)
