What I propose is for me to submit a v3 which squashes Alexander's 3/3
patch (the managed resource changes) into this 2/2 patch.

The alternative would be to extend this 2/2 patch by adding a .remove()
callback only for it to be removed in the next patch which does the
conversion to devres. I don't think that is necessary or even desired.

Alexander, please let me know if you have any objections to this
approach.
