Nope, it's not it.  strict rename only applies to dirs.
I'm writing about plain files, not only rename but also delete.

Enabling strict renames does not change anything.  Yes it prevents from
renaming a directory if a file is open inside.  But not renaming a plain
file which is locked.

oh, you mean just rename a plain file that is currently opened by some 
client? That is possible as long as all opens pass FILE_SHARE_DELETE. 
What kind of "lock" where you referring at in your initial mail?
