Lol, I wouldn't say all crafting should be removed. You could make an argument that a tech junkie class could pull up a crafting bench and make mods to their new arm implant or gun they just purchased on the fly with no issue.
The issue becomes, as you mentioned, the genre blending and mistaking cyberpunk as a post-apocalypse survival. The latter is something beyond the scope of this genre. It would be a boneheaded move to try and implement it across all genres just because it happens to be the in thing at this moment. That would be just a senseless cash grab. If you want that in the game, look for the appropriate mod.
A gun is a gun. It doesn't shoot harder if you add a widget spinner to it. Scopes, extended magazines, laser dots and silencers? Sure but you can just buy those from a shop. As for cyberware? What, tightening the screws will make your gorilla arms do... what exactly? For the rest? You can't exactly start tinkering with your LUNGS.
