It's a small extra complication *for the user*. However, users that need this feature are willing to allocate hugepages. We are one such user. For us, having to deal with packets split into disjoint buffers (from the XDP multi-buffer paradigm) is a significantly more annoying complication than allocating hugepages (particularly on the RX side).
