I would probably support doing that first. A small annoyance is that
the linker requires the --gc-sections option, but most current gnu
(bfd and gold) versions support that, so we should be fine at least on
linux (and the driver already collects the distro we are in anyway in
case we need to change the default for some old distro).

Once that is in,  the existing proposals for splitting sections into
atoms become speed and relocatable object size optimizations.
