I don't think it's entirely unreasonable. It's cheap. It probably works well, if all you care about is a digital signal and if your environment is reasonably noise free. And quite possibly, this is from an older device when cheap and small current sensors weren't even available yet.
Today, you can get neat little current sensors like this: https://www.allegromicro.com/en/Products/Sense/Current-Sensor-ICs/Zero-To-Fifty-Amp-Integrated-Conductor-Sensor-ICs The downside is that it probably costs several dollars, and that it needs a supply voltage.
Or you can bulky non-invasive current transformers like this: https://www.amazon.com/Dwyer-Miniature-Current-MCS-111050-Continuous/dp/B00I9IFJOM Works great, but costs a fortune and is rather bulky.
But the little "ghetto current switch" is honestly not that bad by comparison. If it does the job, then why bother replacing it with something else? Apparently, this is still a common application in household appliances: https://www.reed-sensor.com/applications/white-goods/food-processors/
