but this does not avoid troubles, it just pushes them out to the front-end
developer, forcing him to have multiple branches in his code to deal with
all the variations. I would much prefer to have the major number of the
backend be a contract with the front-end author. If that means we have to
leave some unmaintained backends behind, so be it.
