While these minor features are not used at all in a system sophisticated enough to run ELF files directly, I'd argue that at least COPY will be used heavily in embedded systems as placement of the heap and stack via symbols derived from linker script sections is a common idiom. Overlays are not so common these days but they still exist. It is true that we haven't got a large contingent of embedded developers using the Arm port, there are a few, but I'm hoping we don't scare them away.
