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 If it's a whole package, or a complex function, declaring that it is obsolete means that it won't be developed or supported in the future, and that because of this it might become non-functional at some point because the conditions it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it's a function as trivial as (defun interactive-p () (called-interactively-p 'interactive)) then declaring that it is obsolete means that new code should preferably use the new style.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. Gregory
