I think we could consider postponing this change until the API stabilizes - afaik this and similar APIs have undergone numerous iterations since the initial change, and the synopsis has also experienced incompatible changes (which would render it incompatible even with older nightly builds). Plus since it's only deprecated, imo it's safe to continue using it until v0.10 is released.
