The people who consider the Mac Pro a massive fumble are not the target market and do not understand why the machine exists at all. Apple was never going to make a direct replacement for the x86 Mac Pro.
The current Mac Pro exists only to host Avid HDX cards for ProTools and to host 8K video acquisition cards from AJA or Blackmagic Design.
The instant that neither of those applications need an internal PCI-E slot then the Mac Pro goes away for good.
