This comment falls under the "why don't you just..." cluster. Even implementing a feature like that (assuming it made sense) carries risk (imagine if your limiter's sensor broke and it failed open).

Designing reliable systems is incredibly hard. It requires a ton of resources (money, lawyers, engineers) And experience and long time frames with relentless effort to document everything so that when somebody does die, you can root cause it and fix the problem without regressions.

I've been continuously impressed with what open source hackers have done with open biology projects, but that doesn't mean any of these products are reasonable replacements for the products that are used by tens to hundreds of millions of people.

It does, but just this once it is spot on, the best pumps on the market do just that.

yes, it's spot on, but only a tiny part of a much larger system. And even implementing that feature is devishly complicated. Hence my statement "why don't you just".

Agreed - open body-hacking projects are amazing feats of community and perseverance, but the systemic cost and access issues that plague high-end medicine will persist until they’re addressed systemically.
