ANY noticeable percieved "flaw" in any creative media will eventually become an aesthetic choice.
People remember the emotions the artwork engendered, and thus the whole work is associated with the feelings, flaws and all. If the work is particularly widely known, the flaws can become a stand-in for the work itself.
I see this in video games - I'm fond of the NES-era "flaws" and limitations (palette limits, sprite limits, sound channel limits), but less connected to the Atari 2600 or SNES/PS1/NDS/etc flaws. Shovel Knight is charming; A Short Hike, while great, doesn't resonate on a style level.
I sometimes do something similar on photos, where I darken the edges a bit.
Avoiding vignetting is a trade off between complexity, cost, weight, and other optical flaws. That said modern optical design and manufacturing has made it a lot easier to have nearly flawless (clinical) designs.
