Sorry, I didn't spot the existing bug for this. Merging them.

However, there was some useful information in my bug report which wasn't
in #796925, which is why I'm quoting it here:

The dependency analysis I did in #797618 was for the wrong source package.
Sorry about that, let's try that again:

* there is a circular build-dep with openimageio which will need some
  care (Ubuntu temporarily disabled openimageio support in opencolorio,
  which seems a reasonable solution)
* boost, tinyxml and yaml-cpp0.3 already started their transitions
* Qt does not need a rename
* I think the rest are C or Python and so do not need renames

so the conclusion is the same: I think these two packages are ready to go.

Still true.
