This seems like a really good idea to me. Or at least cap overages at a specified amount, like 2x the free level (a $55 surprise bill is a totally different universe from a $100,000 surprise bill, obviously).

Honestly, this terrifies me---I run a bunch of different sites off netlify, and I would have never imagined that a site could jump from 0 to six figures of bills a month without something hitting a tripwire somewhere and cutting it off or at least communicating with the account owner. At least users should have the capacity to self-impose bandwidth caps to prevent this sort of thing.
