Domino ships with a very recent LibCurl version. It should also make Daniel Stenberg happy and appreciates his awesome work! (he is not happy about the update strategy in Windows).
When leveraging OpenSource at minimum a vendor should keep up with releases.
HCL is doing an awesome job updating LibCurl and OpenSSL!
When 12.0.2 shipped, both have been much more recent then in most Linux distributions (Don't let me started about how Windows handles those two security related, essential components in their products).

Having access to this LibCurl functionality (even it only supports HTTP/HTTPS protocol) would be very helpful for modern C-API applications.
The documentation could point to the original curl_easy documentation.
Just adding the headers and the functions to the lib would be sufficient.
Supporting it could be by a page in the user guide. Avoiding to spend time adding it to the call reference.
This would avoid 3rd parties adding LibCurl into their binaries.
The main request is to allow using curl_easy in Notes/Domino with own applications.
Not sure what side effects an additional LibCurl version would have.
