I think you're looking at it too simply though.
Just because it was not done in the exact vein it was proposed doesn't mean there isn't a way to make it work.
Corpses for example. Say they decay over time and actually become harmful in enclosed locations, like a doctors office. The doctor will then have to get rid of the body, easiest way? WCS or dump it on the street for WCS to come get anyways.
That's just one Idea of how to get over the fact it's totally unrealistic as it currently sits. I have to have a doctor of skill put it into me, but when I die it just detaches from my flesh and sitting with my pile of chyen? Talk about immersion breaking.
If you're more worried about WCS getting the stuff from the corpse, then that's a selfish reason not to make the game more immersive and realistic.
And before everyone says, it just is how it is, then why don't we just make a machine that allows you to buy the cyberware and installs it for you? We are eliminating the doctor element on the uninstall, why not just eliminate it on the install too, since you seem so bothered by being forced to roleplay out the removal.
