The problem was that it wasn’t a “proven benefit†till they had enough data, and there are usually definite (negative) side effects with steroid use. The viewpoint is otherwise reasonable.
As a side note, in drug trials, on rare occasions, where the benefit has been observed to dramatically outweigh the side effect profile, you do see the drug sometimes then being rapidly administered to the control group. A bit more difficult when the duration is short, the data dispersed and the condition not chronic I think, but maybe it answers the question in your mind.
