Comment (by rfleschenberg):
As I understand it, the sentence means this: if the field is not nullable,
the reverse of RemoveField (adding a field) may fail, because Django does
not know which data to add for existing rows.
Apart from that, the forward operation (removing the field) is of course
never reversible in so far as it deletes the data in the field.
Question: would RemoveField be reversible if the field has a default
value?
