I think the discussion is too broad.  It depends on what is declared 
obsolete.

If it's a whole package, or a complex function, declaring that it is 
obsolete means that it won't be developed or supported in the future, and 
that because of this it might become non-functional at some point because 
the conditions it assumes will not hold anymore.  At that moment there is 
a good reason to remove it: it does not work anymore.

If on the contrary it's a function as trivial as

(defun interactive-p () (called-interactively-p 'interactive))

then declaring that it is obsolete means that new code should preferably 
use the new style.  But there is no reason to remove it.
