Like, for example, specifying a file format which doesn't break when
you add things to it (e.g. "The first three tab-separated things on a
line have the following three meanings.  If you find things beyond the
third, keep them with the record even though you don't know what they

I agree here, Peter.  There are a lot of mistakes to be made here, and
it's probably best to have made more rather than few.  So if you're
setting up a team of freed software developers, put your senior member
on specifying APIs.

Or else you'll wind up reengineering things as the Linux project is
doing, e.g. with the filesystem API in 2.1.*, or as the network device
API needs to be fixed (a little).
