FWIW, I still see this on a fresh Ubuntu 20.04 install. My NFS server is also Ubuntu 20.04.

My server /etc/exports looks like this:
/path *(rw,async,insecure,mp=/path,all_squash,no_subtree_check)

My client's fstab just uses 'defaults', nothing else. But here's what 'mount' shows:
10.x.x.x:/path on /path type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.x.x.x,local_lock=none,addr=10.x.x.x)
