Is this really a thing, or are you just optimising for a problem that could potentially happen? Maybe I'm just being naive, but I'd like to think if someone did that I'd quite quickly realise either at interview or on hiring them that they're not actually capable of doing the job by themselves.

Not sure. The whole idea of the test is to get around people that talk well vs do well.
And assuming the friend told them about how/why they did something the interviewee can talk about this solution as if they did it. How would you know? See I'm assuming the 'friend' adds value to the solution to make it amazing, and the person who is interviewing still has average knowledge so its not like they are completely winging it.

Absolutely. You should optimise for problems that could happen if they have reasonable likelihood and will become significant issues if they do happen. Not going to rule out all issues. Thought this seems a likely risk over a reasonable number of candidates.
