MS always wanted 8GB but GDDR5 was not available to that amount when they designed the Xbone project... so the only alternative for MS was use DDR3 with eSRAM to avoid the possible bottlenecks.
They are paying for that decision with yields issues created by a big, complex and expensive APU.
I'm sure if at time of project the GDDR5 was available to 8GB then MS may use GDDR5 instead DDR3... they used GDDR3 for 360.
So to reply your assuptions in OP... MS needed GDDR5... without it they have to go in another path not easy.
PS. Why did you try harder to defend the bad MS decisions?
