I feel like the fact that the phone-with-removal-battery option already exists and is not popular in the market should be a signal to EU politicians about how much the public actually values this capability.
Usually, in consumer electronics, the unencumbered market tends to gravitate toward what people actually want to buy. Totally possible this could be an exception to the rule, but I doubt it.
In the absence of such phones, I compromise on adding a cover.
It's an extreme example, and way too bulky for most people, but the point is: "rugged cellphones" absolutely exist.
Also I don’t need fully ruggedized. Just enough that a cover would be superfluous.
