The problem simplicity is facing is mentioned in TFA with the keyword "future-proof", which is the typical instance of FUD in software. It is extremely difficult to fight against it, as, just like fake news, it would take 10 times more effort to debunk it than to make it. Yes, you spell out the cost of the additional layer, but it is invariably answered with "that's not so expensive", and risk aversion does the rest.
