You seem to be trying to say that section indexes between SHN_LORESERVE and

I think you need to qualify what you say. It is clearly true that the st_shndx

indeed reserved. The ELF ABI defines what to do for a symbol

Don't confuse the notion of section index with the special codes between
SHN_LORESERVE and SHN_HIRESERVE. Those special codes are used in the st_shndx
field of a Sym structure. They are not meaningful elsewhere

That means we can't use from SHN_UNDEF and SHN_LORESERVE to SHN_HIRESERVE

No, it doesn't. It only means that you can't use them in contexts where index
size is restricted.
