Support generate elm api as HttpBuilder ?

[hjmtql]

Now it seems generating elm api is as only Http.
http://package.elm-lang.org/packages/elm-lang/http/1.0.0/Http

There may be something like that Want to add some header parameter

But Http (unfortunately...) insists that Do not support for modifying existing request
(it means generated request code cannot be modified)
ref : https://github.com/elm-lang/http/issues/27

Against this kind of problem,
I think support generate elm api as HttpBuilder (extra Http library) is one of a flexible solution.
http://package.elm-lang.org/packages/lukewestby/elm-http-builder/5.1.0/HttpBuilder

What do you think about this ?
