RFC 8881, "Network File System (NFS) Version 4 Minor Version 1 Protocol", August 2020

Errata ID: 6865
Status: Reported
Type: Technical
Publication Format(s) : TEXT
Reported By: David Noveck
Date Reported: 2022-02-28

Section 18.25.4 says:

The server MUST NOT delete the directory entry if the reply from 
OPEN had 
the flag OPEN4_RESULT_PRESERVE_UNLINKED set.

It should say:

If the reply from OPEN had the flag OPEN4_RESULT_PRESERVE_UNLINKED set,
The server 
MUST NOI delete the file contents until each directory entry is 
deleted and the file is no longer open.

Notes:

The existing second and third bullets are directly contradictory.
