Vue.js: Closing Gaps Between Compile-Time Assumptions and Runtime Reality
Three fixes landed today that each correct a case where Vue's tooling or runtime made an overly narrow assumption—about template languages, plain objects, and render timing—causing false warnings or broken behavior in valid code.

Good morning. It's July 8th, and today's Vue core activity centers on one theme: edge cases where the framework was too strict, breaking valid patterns developers actually use.
Start with PR 15054. The script setup compiler was skipping import usage checks for templates written in Pug, because that check assumed a standard HTML-like template. Contributor ifer47 fixed this by preprocessing non-standard template languages before running the existing identifier walker, so imports used only…
Same author, same day, a related fix in PR 15053: "toRefs" was throwing a dev warning when called on plain objects, even though that's exactly what "script setup" produces internally when you destructure props with rest syntax. The false warning has been removed, with test coverage confirming plain objects and plain…
The third fix, PR 15052 from Askerka00, addresses a timing bug in template refs. A functional ref on a parent couldn't access a child component's exposed elements because the child's internal refs hadn't resolved yet. The fix defers functional ref invocation to the post-render phase, but only for stateful…
The common thread: each of these bugs came from Vue making a narrower assumption…
