Yes, the deployment looks like a lengthy and risky operation. But the risks don't end there. The Northrop Grumman cryocooler has been a major problem for JWST, requiring years of development and rework. If it fails then some of the most crucial instruments are useless.

This is a good comment. The deployment is eye catching, but the cryocooler was the high technical risk item.
