I'd don't get the increase wear argument. For 11spd drivetrains, average chainline stays static. For 10spd 1x converts, there are no changes in chainline. The argument of spending more time in the 36T cog is nominal, since it is likely you spent the same amount of time in a 36 rear / 32 front if running a triple setup, and only shifting down to the granny once in a blue moon.
When compared to true 2x setups, the 1x drivetrain setup actually improves since you spent most of you time in the bigger of the two rings, but that bigger ring (32-38T size most likely) actually sits in between the middle and outer ring of a triple crankset,making the chainline worse when staying in the 36T cog.
Furthermore, for riders opting for the Race Face 30T narrow wide ring, the design parameters move the ring inboard of the usual position, improving the chainline in the easier gears, which is where most 1x riders keep their chain while riding.
If anything, 1x improves the average chainline and theoretically increases chain life.
Personally, I could care less about chainline. Dust, dirt and mud are much more detrimental to chain life than chainline.
