No. Composite framework only makes it relatively simple to create such
gadgets, but one still needs some glue that binds all the functions into
a single gadget.

This seems like both a blessing and a curse (which I haven't realise when
I was creating g_multi) since with n functions implemented one can easily
came up with 2^n gadgets.

Android went half-step forward and in it you can create a gadget by
specifying list of named functions it is supposed to have. I'm saying
“half-step” because they have no support for configurations for instance.
