There are plenty of HTTP libraries for Node.js. request and request-promise have to stay, because there might be some Cloud code using them that was written before they were deprecated.
In our sandboxed environment you have also quite popular superagent. bent is a quite fresh library and its not even mentioned on the list of most popular HTTP request libraries.
I would like to have some more users support that bent is the library they would like to use and not others from mentioned list.
