I find it interesting that I was actually directed to your question by Canvas support after asking why these features are missing.
To answer your question, no, the Ctrl-K dialog has now changed. The only options available are Text and Link.

I sent in a support ticket about the other missing features and received an invitation to post a feature idea on the Community and a link to this very question. I find it utterly disappointing that not only do they know this question has been asked, but have no answered you. Additionally, putting in a feature request for something that previously existed and was a great help to our faculty is a bit absurd.
