In the KB article describing this change Microsoft says it introduced 
handling of "userinfo" in HTTP[S] URLs in IE 3.0.  That was what -- 
1996 or 1997?  Whatever, I think we'd agree that in computing or 
Internet terms that is a fair while ago...

As has been discussed (at length) in this and obviously related 
threads, the change in IE specifically affects HTTP and HTTPS URLs.  
IE's handling of FTP URLs is irrelevant as the "userinfo" syntax is 
allowed for such URLs and is not claimed to have been altered.  
Microsoft has simply, very belatedly, pulled this aspect of IE's 
behaviour into line with the standards that define what an HTTP[S] 
protocol handler should do.
