Pacemakers need to be replaced every 5-15 years as the battery wears out [1]. It's not like a visit to the dentist either, it's a major surgery. I also think you underestimate how rapidly a medical device company can make a dramatic change to the design, have it tested and approved, and distributed inside everyday people. Yes it's "coordinated" but the timeline is extremely long compared to how often the phone market is being pumped full of magnets.
For what it's worth I think it's still up to the user to be safe and know what they can and cannot have up against their chest. But to say that the medical community can just be "agile" about this is to really misunderstand how those devices are certified and designed.
