The obvious question is here, and for IPv4/IPv6 - should the wireless
stack be responsible for doing this instead?

The upside of this approach as-is is that all other protocols can easily
be extended to do this and no protocol-specific code is needed in
wireless; the downside is that it clobbers all protocol code. Thoughts?
