the python-pip package bundles python-certifi binaries when built. After updating python-certifi, a no-change rebuild of python-pip is required.

While the cacert.pem file is shipped in binary packages, it is not used in any way, the actual application is patched to use the system ca-certificates. There is a Debian bug filed to remove the cert store here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=947287
