i went back a few years in the sphinx docs but couldn't find out when exactly the syntax changed which seems to suggest there is likely no issue regarding backwards compatibility...

Hi,

Perhaps is better use https and "/3" in the URL. The mapping could be done with "python" instead the "http://www,python.org/"?

Something like:

intersphinx_mapping = {
    'python': ('https://docs.python.org/3', None)
}
