First of all, it's great to have you here!
I totally agree with you that people shouldn't be afraid of heavier gears, but I disagree with your statement about the chain line.
My typical enduro rides are like 2hrs uphill and 30min (fast single tracks) to 2hrs (very gnarly alpine paths) downhill. In both cases, the whole drive train is far more stressed uphill than during the downhill. With my old 2x setup (22/32 and 11-32) , I mostly used the 22 chaining and the 4 smaller gears at the rear (22-25-28-32).
Considering that, riding a 32t chain ring in front and mirfe's 42t chain ring at the rear with a 50/51mm chain line of standard 3x crank sets, will definitely get me a chain line not ideal for the gears I mostly use. Moreover I think that due to the higher number of chain links sitting on the two bigger chain rings, the whole drive train will be more sensitive in terms of skew of the chain.
So, my conclusion is that optimizing the chain line for the most used gears makes perfect sense. The resulting skew at higher gears (11-16) is acceptable for me, since I don't apply the same amount of constant pressure on these rings and the skew of the chain is generally not that problematic on smaller chain rings.

?!?
Du, das war ein Extrembeispiel *g* Um so lang runter zu fahren muss man entweder super lahmarschig unterwegs sein, weil's dort eben nicht schneller geht, oder man trägt bergauf noch ein Stückerl, aber dafür ist mir die Kettenlinie wurscht.
Sobald ich allerdings im Gelände bin ist die Übersetzung perfekt. Das 42er wäre nur für Alpine Touren mit richtig langen / steilen Anstiegen, mehr wie 28 / 11 brauch ich selbst auf den schnellen Passagen nicht - aber da hindert dann auch eher das Fahrkönnen. Wobei ich mit 42 hinten wohl ein 30er an die Kurbel montieren würde.
