That's why the doc says:

   [..]
   should stay as the outermost advice.  When two advices specify the
   same depth, the most recently added advice will be outermost.
   [..]

She can't do it and hope for it to affect already compiled code, indeed.

But we use advice-add in cl.el on the `declare', `dolist', and `dotimes'
macros and it works very well.  Obviously code that uses those needs to
have a (require 'cl) somewhere to make sure the advice is installed
before macro-expansion.
