Among the many changes, the new rules would require batteries in consumer devices like smartphones to be easily removable and replaceable. That's far from the case today...
It makes it more difficult to design really thin phones because the battery needs a sturdier case and an additional connector to be easily replaceable. Generally making a phone smaller and thinner makes components less accessible.
Personally I think it is more important that high quality batteries are available for a long time.
In my opinion it would be fine if some tools were required to replace the battery. Ideally that only needs to be done once every 2-3 years so if it takes a bit longer it isn’t such a big deal as when there aren’t good batteries available.
