I guess I'm not sure what sort of explanation you are seeking.
The overhaul you mentioned is already being done.  Were you assuming
that it was not?  Were you thinking it would be easy?  Is there
an assumption that Wolfram Research is somehow unaware of the
limitations of this technology?

Perhaps I am misunderstanding something here, but it seems as
if the requested explanation may in fact be a progress report on
internal research and development efforts, so that everyone can
see what is being done and what is not being done and why, and can
assess for themselves whether the priorities are to their liking.
Other than being a lot of work I'm not sure what that would reveal,
except that different people have different priorities.

More generally, although I don't want to make light of the concerns
expressed in this thread, I'm still a bit unclear on what could
realistically be done in response and that is not already happening.

Is the Assumptions facility in Integrate one of the examples that you
have in mind?  It is not at all clear to me how this can be "fixed",
although there are some promising possibilities, any of which will
involve a lot of work.  I am not myself aware of any problems where
there is not (what I would consider) a "good explanation".
