That's a good advice in general to treat any software as untrusted black box as much as possible. But it raises (slightly, but still does) the cost/effort for the user: the user now has to make extra steps and take extra caution.

These concerns were great valid even before vibecoding becoming a thing, but now the estimated probabilities of malicious code's presence have changed, simply because nowadays the cost/effort of writing software plummeted.
