The 2018 car was more instable than the 2017 because of the bargeboards not managing airflow as expected, it wasn’t because of the change from the Honda engine to the Renault engine allowing more diffuser area... You are speculating that and isn’t fact based.
I also disagree that “Ultimate Aero Performance” (which is I guess your own personal concept) has anything to do with the engine layout per se... It is well known that Red Bull had over the years the best if not one of the best chassis and aero on the grid and they did so with the Renault engine/layout.
The 2019 was a large scale redesign because of the rule changes really... The bargeboard area had to be redesigned because of the new regulations in regards to it’s height, the nose front wing of course had to be redesigned due to the new regulations while the nose was the same or an evolution of the 2018 one... The only major change for Mclaren was the location of the crash structures from top mounted to bottom mounted... But beyond that, the changes seemed to respond to the changes in the regulations.
You sure about that? The 2018 bargeboards were an evolution of the 2017 ones, which weren't as good as the other's to begin with.
Red Bull was able to have good chassis performance in spite of, not because of the power unit layout. This is evident by the large swings in performance they would have mid season, always playing catch up due to fixing issues with the chassis. Part of the reliability problems were due to extreme packaging Red Bull had to use to get the desired aero performance. McLaren's 2018 season was partly compromised by the cooling requirements of the Renault engine interfering with the cooling requirements of the gearbox. Issues which were largely addressed in 2019, and still again in 2020.
Red Bull managed to have the best aero performance of arguably the whole grid (given that they were using what wasn’t the most powerful engine at the time) with the current Renault engine layout... Which disproves
that you can’t achieve best of the grid performance with that engine layout.

Strong words, this is the McLaren topic, I'll only say that Red Bull's 2018 performance was flattered by circumstances. They earned every win they got, what I mean is yes they had a good chassis, and the weakest link in their chassis performance was always the Renault engine. That is what failed. Why did it fail? Because Red Bull designed their own cooling and rear end, which wasn't always compatible with the limits of the Renault machine. Which is why I say their performance was in spite of, and not because of the Renault engine.
What we have seen in 2019 is that the Red Bull had more than adequate cooling for everything and nothing broke this year, despite this conservative approach they still surpassed 2018's chassis performance. 2020 will be even better as they will push things more to the limit for the aero performance it brings.
Yes McLaren will certainly be better, but I maintain that if you go too extreme with the rear end, the Ferrari/Renault layout has more trouble dealing with it, than a split turbo setup. In 2019 the Ferrari/Renault layout had the lowest chassis performance, the Ferrari/Renault layout did much better on drag limited circuits vs downforce limited circuits. McLaren did very well, and has a chance to make another big step, this is obvious. However with a Mercedes power unit with a split turbo setup they have a chance to take an even bigger step.
If McLaren were happy with what was possible with Renault they would have stayed, because the Renault power unit is now relatively on par with the others, and will be even better in 2020.
