nice idea with this field versioning - easy to follow and see what is new and in case of more changes needed can be still possible to follow without making diffs on those files

in my example I used obligatory field - I think I tried to specify as optional first and later redefine to obligatory but that indeed would be incompatible schema evolution. (not sure if that will matter but just mentioning)
