The apps/use cases for which such standardized and opinions tools can exist for, economically, mostly already exist IMO. Vibe coded tools fill an enormous space of semi-unique problems that only affect a small amount of people. For example various scripts to automate tasks imposed by a boss. The best balance is probably to use LLMs to use the standardized tools for you when available, so that things remain mostly scrutable.

As the saying goes, 80% of users only use 20% of the features of your program, but they are different 20% parts. When the user vibecode the program instead, only their specific 20% needs to be implemented.
