ok, ty

More precise: Currently not.

At some point in the future we might see a new unified version that
will run on a number of cameras.

We have had that before, and if I interpret A1ex right, he is currently
using a unified version for at least both 5D Mk2 and 5D Mk3.

This will likely find it's way into a new unified version. Some time.
And don't ask when, it will be available when it is finished.
I'm pretty sure that not even A1ex can say when this will be.
