I asked, poorly as I didn't specify growth rate, about fixing the Yor in the dev stream because I thought the devs knew about the problem but Paul didn't seem to know what I was talking about. So to make this clear, all of the synthetic growth rate techs don't work.
I will try another game to verify but my first game in Beta 5.3 I didn't see any change, every time I researched a new syntheric growth bonus I checked assembly and always stated 101 manufacturing or 1515 credits to finish at full, the power buildings also have bonuses and after building them still no change, 1515 credits to buy or 101 manufacturing.
My belief is that the bonuses are still pointing to the Assembly project and hence my asking for it to be reinstated if the pointer is not corrected.
