Ultimately I'm fine either way. I do think that in the past few months of review it has become clear that creating this tls abi requires a fair bit of work. It'd be a shame to see a future attempt to use such an ABI made difficult by forcing the author to figure out the registration process yet again. I assume the maintainers of glibc would also like to avoid the need to register multiple ABIs.
