Lots of features are added to DPDK all the time, and they all use the same "insignificant performance impact" argument. But the fact is, each added test-and-branch has some small performance impact (and consume some entries in the branch prediction table, which may impact performance elsewhere). If you add a million features using this argument, there will be a significant and measurable performance impact. Which is why I keep insisting on the ability to omit non-core features from DPDK at build time.
