Hi, I'm one of those people in the PR advocating for this change :) I think you may have missed the point of comparing the security aspects to NPM. By saying "it's no less secure" it's not saying "well it's just as bad, so what's the point?", but rather "given that it doesn't introduce any more vulnerabilities, what does this model unlock for us?"

HN comments probably aren't the best place to go in-depth on this topic, but just off the top of my head, HTTPS imports allow a greater detachment from a centralized registry, something we're seeing used a lot in the Go ecosystem, and we're moving server-side JavaScript closer to how browser JavaScript works, which is a good thing for anyone using the language, as it reduces friction across the board. This might not be something obvious for people working mostly/only on the backend, in which case those frictions aren't as apparent, but they are there nonetheless.
