Why nfs/nfsd kernel modules were removed from linuxkit?

Hello,
I am particularly interested in running nfsd server in docker container on the mac and mount nfs shares from other containers.

This has nothing to do with native nfs.
For some reason I see that nfs/nfsd were removed in latest Docker 18, so my projects stopped working.

Is there an easy way to modprobe these modules for good without recompiling linuxkit kernel?
