I think our fascination with Coral Reefs lies in the similarity to humans, in that it's just one giant colony of living beings that group together to form one large life-form. All they need is a central organism with a method of communicating to the whole, and they're essentially water-people.

The suggestion that reefs might be saved by engineered or selected varieties 'farmed' by humans shows a lack of understanding of the massiveness of the problem. This isn't one, 20 square mile reef, which in itself would be completely impossible to 'reseed', this is the entire ocean.
Also, there's absolutely no way to select for varieties that can still make calcium carbonate in acidic waters, the chemical processes just don't happen, so selecting for heat tolerance only addresses one tiny part of an intricate, multifaceted problem.
I wish I could be placated by the idea that people are working on and will solve the problem(s), but I simply know better.

A handful of people can't put a dent in a hundred years of billions of people's damage.
