In that case, shouldn't unsafeCoerce be in Data.Unsafe? It seems odd to 
have a Unsafe.* hierarchy if it's not going to have all the unsafe 
functions.

Unsafety is a bit different from the other categories. Deprecated 
functions by definition shouldn't be moved, only deleted. Portability 
changes, and so does standards-compliance, so there's no need to move 
such functions around.
