Not quite. For example if an st= tag is in the header and the signature  
verifies, then you know that tag was put there (or at least was present)  
when the signature was made, and was not inserted by some  
scammer-in-the-middle.

That is an essential feature upon which future versions/whatever can then  
rely.
