This is essentially what PEP 470 proposes, except that the link says
"this project is hosted on this external index, check there for the
relevant details" rather than having individual links for every
externally hosted version.
Well, not quite. The PEP proposes a link to a page for an index with arbitrary contents. The above would link only to packages for the /simple/ name in question. A very small amount of protection against accidents but some protection nonetheless. Also, an installer does not need to go to that external index to find anything - everything is listed in the one place.
This is still a second mechanism that users have to know and be aware of. The multi index support isn’t going away and it is the primary way to support things not hosted on PyPI in every situation *except* the “well I have a publicly available thing, but I don’t want to upload it to PyPI for whatever reason” case. As evidenced by the numbers I really don’t think that use case is a big enough use case to warrant it’s own special mechanisms. Especially given the fact that it forces some bad architecture on the installers.
