I do not think that would help much. DDT is not just any old program,
it is conceptually part of the OS because it reads and manipulates
internal OS data structures - which other programs are not allowed to
do. So, that means that each time any relevant internal OS data
structures have changed an updated version of DDT is required that
knows about these changes. Such changes of internal OS data structures
can happen at any time without notice because they are not visible to
user programs. So, due to the way DDT was written it needs to be
maintained alongside the OS, but that only happens for RO5 now.
