Because evidence based medicine is often about broader problems, medicine 3.0 is about solving problems for a specific person. It could be a rare type of cancer that a specific treatment has been crafted for that person - in this case theres no evidence to say that exact treatment works, maybe the over arching therapy is backed by evidence but it feels like a trend away from needing strong evidence to back the application of the therapy.

How is treatment crafted? Will waving a crystal stick be a part of it?

Literally all medical practitioners are trained to take individual people circumstances into account.

Taking individuals circumstances into account isn't evidence based medicine though...
