      (Note that side python-dash-*-components have been deprecated upstream
       in favor of the embedded version in python-dash.  The below is probably
       not necessary, but just in case, this is pushed on salsa:
       https://salsa.debian.org/med-team/python-dash-html-components
       https://salsa.debian.org/med-team/python-dash-core-components )
