Ah, your interpretation is incorrect. The server says "this is a script" and
the client is required to treat it "as a script." THAT DOESN'T MEAN that the
client must execute it; nay, the client should decide what to do with it,
and a smart client with initiate safety precautions and NOT exectute it
unless the user explicity overrides the safety.  

But the clients shouldn't, for example try to open a script that the server
said was a script in Word or Excel, that is unless the server served as
application/msword or application/vnd.ms-excel, respectively.

	1 Summary of Key Points
		* MIME headers sent by a server are authoritative. [Design
choice]
		* User agent behavior that misrepresents the user or the
server is harmful. [Principle]

The document is short and worth reading if you haven't previously read it.

Ultimately we are saying the same thing, but we got there via different
paths. In many case, the path is very important as, in this debate,
described in the referenced document.
