This is where "make it easy to test" comes in.

And, sure, there are some things that are easy to anticipate. If you're processing CSV, you may get asked to process arbitrary delimited files next. But the point is 3 - 5 years out, you'll get asked for something the current architecture cannot support and a major effort will be required. You cannot anticipate those and thus should never try to.
