I take the opposite approach - bundling is a non-starter for me. But it really depends on what you're building. Bundling can be great for web apps, but for content-driven websites where SEO optimization is key, I prefer the "90s-style" approach and Fullsoak's philosophy.

Also, separate HTTP requests allow for granular caching, and with HTTP/2 the overhead is minimal.

You're doing the opposite of SEO optimization if page speed score is of any value to your SEO (and it's important to Google's SEO ranking, so yeah). I work on a "content-driven website" - actually a few thousand of them - and our clients definitely want their SEO to be top-notch and page speed score factors into that. Any http requests for external resources will bring page speed down, and that can affect SEO. I don't have to worry about caching at all when the pages are scoring perfect 100% on Lighthouse.
