And now imagine a big company develops a software interacting with yours at point 2, and finishes it at point 5.

You’ll have to add backwards compatible wrappers that emulate an older API in 7 and later.

Or you can actually test with proof-of-concepts, with mockups, with other tests, before you even write the design.
