I'm not going to express strong opinions here, but their name implies
that this can happen, some time in the future.

And I also think it will not happen before the userspace part
(libusbg, gt, gadgetd etc) is mature enough. My personal opinion
in that matter is that it will take at least a couple of years
to remove legacy gadgets entirely.
