Most of those features were completely gone by 1995, leaving
larger address space as the sole practical benefit and no actual
transition plan.  This wisdom of this approach is questionable at
best, and I'll admit to being part of the team that went along...

However, even with just bigger address space, there *is* a real
problem that will be solved by IPv6, and that's avoiding the even
larger chaos that results from true depletion of IPv4 space for all
ISP's who need more space for their growth.  I've already ranted
about this here and on ARIN PPML, so see the attached link for
one answer to your question.
