That seems excessive to me - at least, I don't see how SOLID principles necessary lead to that outcome even if strictly followed. What is it about those principles that prevent classes/interfaces that have a handful of related methods, like a StaleJobsService or whatever? For all of the OO patterns, they have a common rule that says to not use them unless they actually solve a problem / code smell.
