I think it's more practical in terms of being used for layering with kevlar to reduce overall weight of a piece of body armor. While at the same time making it cheaper and more cost effective than traditional body armor materials as mentioned in the article.
So rather than this being used as an upgrade to kevlar (which with more testing it might be able too) it's more like a side grade to reduce costs, as mentioned in the article silkworm silk is already used on a commercial and industrial level for other applications.
Granted it'll probably be a good few years before the silk being made by these genetically modified worms is both made consistently and is more refined with further testing and then distributed. But still it's something that material scientists will likely put to good use for reducing costs in lots of fields.
