Loren Stewart's framing: rather than picking between the 'toy' low-complexity end of pure server-rendered HTML and the 'serious' high-complexity end of full SPAs, developers should treat frontend complexity as a gradient and start near the top (a bit of JS here and there, Hotwire/Turbo/Stimulus-like tools), only moving down the stack when there's concrete need. Resist complexity and refactor back to simpler approaches whenever possible.
