Seems boilerplate "could be helpful to cure xxx" statements written in press releases and grants for most research findings; neutralizing antibodies do seem to help in mitigating worse outcomes (among others Lily sells a concoction) but even when they have good half lives it looks like the neutralizers don't do too much; there's no benefit I can see for something with orders of magnitude lower half life still.

“Could be” in this context is more like “hasn’t been conclusively proven impossible”. Unless somebody is taking about human trials it is exploratory and not worth getting anybody’s hopes up unless your hopes involve grant money and publishing papers.

Mostly hype.
