FEATURE_WGET_HTTPS is controversial. FEATURE_WGET_OPENSSL is a cool option when applicable. some distros, such as DD-WRT std, have a working cURL (including CA certs) but incomplete openssl. for those it would be great to have a FEATURE_WGET_CURL flag to offload HTTPS to cURL and make it secure. (right now it uses FEATURE_WGET_HTTPS, which clearly is an inferior option.)
