There are so many stories in the history of spaceflight of deployables not deploying, so it's completely believable that they didn't work. There are stories of astronauts kicking them, satellite operators jostling and gimbling and heating them, limited performance from partial failures...

Bigger cheaper rockets should hopefully mean less JWST Rube Goldberg style satellites because the extra volume and mass can be put to use. But it probably just means even bigger deployables...
