The article's kind of confusingly written (not exactly unusual for articles on any wiki), but it does indicate in the 2nd paragraph that RICE is no longer indicated for the promotion of healing. It does cite several articles suggesting that, while it can reduce pain and swelling, this is not associated with faster healing.

I'm no physician, but as a child I did spend many Saturday afternoons watching Dad prepare lecture materials for the med school classes he occasionally taught, so I think that I am probably as qualified as a non-physician can be to massively overestimate my own competence. And I certainly don't know anything about soft tissue injury and inflammation beyond what my physical therapist has told me. But in the classes on research methods that I took in grad school, we loved to pick on the mid-to-late 20th century medical literature and standards of care, and one of the common themes that cropped up was a tendency to over-extrapolate.[1] That might be part of what happened with RICE? A strong acute histamine response might be associated with some secondary cellular damage at the injury site, but that's not necessarily a bad thing for long-term outcomes.
