- Font formats, as well as other Mime types, are not only used by Web 
browsers.
- There may be new formats, for which no sniffing is done yet.
- Servers may prefer to declare what they are sending out rather than to 
be silent about it, even if not all clients use that information.
- Once we have registered types, sniffing could in the long term maybe 
even go away.
