> And how much complexity and engineering effort and bugs are you willing to tolerate to halve your memory allocations?

You seem to be confused about this relationship. It's usually exactly the opposite.

The wasteful applications are generally not well reasoned about and half assed implementations. That's why they're guzzling resources

There is ofc a middle ground, because targeting eg incredibly resource constrained embedded systems will naturally increase complexity, but that's something entirely different to the scenario this discussion was about up to this point.
