Just to understand it, a call with this new parameter would look like
the following example?

EXPORT PASS_SSL=--pass somesslpassword
EXPORT PASS_PROXY=--proxy-user someproxyuser:someproxypassword

curl --proxy myproxy.xy \
      --config-env PASS_PROXY \
      --cacert serverchain.pem --cert client.cert\
      --config-env PASS_SSL \
      https://www.some_secure_server.xy
