Another possibility for fashion ain't gonna harm anyone.

True.

Though i still think the excal bit you suggest is really not needed. Due to the shear quantity of fashion he already has. Especially compared to other frames.

Newly released base frames have also been getting increasingly complex over time. I assume that it's just an overall design trend that's more noticeable for prime versions because you have an older base to compare to.

I dont agree, the old primes just look like a recolor, since chroma prime almost all primes are really cool, and i hope some day DE revisit the old ones and give them a new look, but keep the old look as a skin for the people that prefer the old version.
