Providing new functions with added functionality cannot break any existing
programs. But embarking on such a venture requires energy, intitiative and
presence of clear mind which not everybody has.

Another problem is that even if you provide the possiblity for new applications
to run protected within the environment, the fact that older programs cann still
jog around the address space and wreak havoc, defeats the initial purpose.
Either you provide memory protection to everybody simultaneoulsy, or you
don't at all.
