This seems similar to nfsd, which is only present in many UNIX implementations to prompt the kernel to service NFS requests.

A lot of (local) filesystems seem to do this as well (XFS in particular).

A lot of kernel code spawn threads. I was not aware that it can also spawn usermode processes running code embedded into the kernel. That should be advertised and developed more IMO. Tons of drivers should have nothing to do in kernelmode.
