Sure --- see remote-curl.c.

There's also the "connect" capability. builtin/remote-ext.c and builtin/remote-fd.c are examples using that one.

It mainly has to do with what it is convenient for your helper to produce. If the helper would find it more convenient to write native git objects (for example because the remote server speaks a git-specific protocol, as in the case of remote-curl.c) then the "fetch" capability will be more convenient. If the helper wants to make a batch of new objects then a fast-import stream can be a convenient way to do this and the "import" capability takes care of running fast-import to take care of that.

Thanks and hope that helps, Jonathan
