Sure they do, if they want uid/gid mapped properly.....

Here is the output from an F16 system showing the effect....

First I mount with no rpc.idmap service running....

[root at f16-1 ~]# mount -t nfs4 192.168.0.55:/syntegra /syntegra
[root at f16-1 ~]# ll /syntegra/
total 40
drwxrwxr-x. 3 4294967294 4294967294  4096 Mar 24  2010 HP-Pavilion
drwxr-xr-x. 9 4294967294 4294967294  4096 Nov 30 10:21 iso
drwxrwxr-x. 7 4294967294 4294967294  4096 Nov 30 10:34 linux-releases
drwx------. 2 4294967294 4294967294 16384 Apr  1  2007 lost+found

And...then....

[root at f16-1 ~]# umount /syntegra
[root at f16-1 ~]# systemctl start nfs-idmap.service
[root at f16-1 ~]# mount -t nfs4 192.168.0.55:/syntegra /syntegra
[root at f16-1 ~]# ll /syntegra/
total 40

drwx------. 2 root     root     16384 Apr  1  2007 lost+found

Notice the difference?
