I think the best answer is that it is under study and good science takes time. Initial indications are positive but anecdotal. More data is needed. This is from Dr. Fauci yesterday.

There is reasonable hope for better treatments from a range of drugs but for each one you need quality studies to determine the effect size, dosage, risk/benefit, and statistical significance. If we can slow this pandemic we will have more time for the science, plus many other preparations that are happening in hospitals.

Wash your hands, limit social contact, stay informed.

Here's a review of one of the papers that has been causing some of the hype:

My layman's understanding is that there is theory to support it and some treatment centers are trying it out, but there isn't quality evidence to suggest wide spread adoption.

Good question, seems like it's still being determined, but apparently the US president has made some statements that suggest it does. Being a doctor does come naturally to him of course.

Serious question? People still don't follow relevant news, do they...

The evidence that it helps as a treatment is spotty.
