Planned reuse has been widely discredited in software development, especially after the Big Push For Reuse that we saw in the 90's.
Writing code on the basis that it may be applicable in multiple future scenarios is speculation, and speculative generality is considered a code smell. The danger is that when the future comes, the reusable generalisation we planned turns out to be not quite what is actually needed, or doesn't quite fit all the scenarios, or - more usually - that the future eventuality never comes up.
Software development is hard enough when we have to write code that satisfies today's requirements. Adding in a whole bunch of "what if?" code makes it even harder, we have found.
