I'd strongly advise against folks doing it statically.. there seems to be ongoing issues with stale filters each time new address space is released. Even with the best of intentions folks change role or employer and things can get left unmanaged.

The craziest stuff that gets announced isnt in the reserved/unallocated realm anyway so the effort seems to be disproportional to the benefits... and most issues I read about with reserved space is packets coming FROM them not TO them....
