p4lang projects behavioral-model, ptf, and p4c have used nanomsg for many years. There is no urgency to replace nanomsg.
nng [1] [2] is a successor to nanomsg. While it supports compatibility with some parts of nanomsg, e.g. it installs header files in directory <nng/compat/nanomsg> that have the same names as corresponding include files in nanomsg, nng does not as o 2026-Apr-06 implement the function nn_symbol, which is used by behavioral-model code. The new function nn_symbol_info might be provide a superset of its functionality, but this would need to be examined and tested to be sure.
The draft mode PR #1364 might be useful as a starting point for developing a full working PR that replaces nanomsg with nng, but I am not knowledgeable enough about the details to know whether discarding it and starting from scratch might be more productive.
