If anyone has any clearer diagnostics about what version of wireguard introduced the errors for the older kernels, or (even better) what specific change seems to cause the incompatibility, then that might be useful for further debugging.
I actually found wireguard-dkms_0.0.20190123-1_all.deb on the affected server indicating that I'd previously manually installed and used it. Trying to compile it fails with the same error, making me think that the problem cause is somewhere outside of Wireguard itself.
