I think this issue started when some of the Go developers questioned
why the kernel needed to provide a very complex interface--parsing an
ELF shared shared library--for very simple functionality--looking up
the address of a magic function. This approach has required special
support not just in Go, but also in the dynamic linker and gdb, and
does not work well for statically linked binaries. The support in gdb
is perhaps a good idea, but elsewhere it does not make sense.
So why not provide a simple interface?
What good would it do now that everyone already supports it?
The proposal is 10+ years too late.
