Artistry should be involved in the quality check... But not the check to customize. From there it would be up to players to self police. Similar to gangers with graffiti.
Want custom cyberware that will be able to be exposed at a operations meeting?
Need someone who either contracts with an artist for designs. Or is an artist themselves.
Want someone who can erase that nasty logo on your cybereye and make it look natural?
That's gonna take a decent artist, and a decent cyberdoc.
Just like every other method of creativity, from how you style your hair, to how you do your makeup, should be influenced by your artisty. Or someone elses direction and artistry.
Artistry is a wide ranging skill for a reason. As are literally all of the other skills in it's category.
