The Twitter hero faction of the Python core "developers" (many of whom have not done much actual work for a decade) has always been pro-web and anti-C-extensions.
They have been peddling the dream of speeding up Python by neglecting the scientific ecosystem for a long time without having either the expertise or a clear plan how to achieve that.
All that while the primarily useful part of Python is its C extension capabilities. The web does not need Python, query/response applications are handled just fine and better by functional languages.
