Did they eliminate pop based lag?

Hi guys, stellaris veteran here, played on and off since release but I haven't got on since 4.0 launched, now that I hear 4.3 seems to be heading in a good direction is there any *perfomance* reason not to max out logistic growth ceiling and minimise growth required scaling in the new game options?

I have a solid system, not quite best of this generation but still beefy. I always wanted to roleplay an overpopulated mess of an empire.
