You also get error checks for incorrect type operations:

This is not by chance, the whole framework was built around that design.

And it was thoroughly tested at the design phase, before any implementation, to ensure it would work with all the editors.

			// report encoding bugs to AWS, and use ASCII-only metadata to ensure reliable S3 API
			// compatibility.
			if needsMimeEncoding(v) {
				// see https://github.com/golang/go/blob/release-branch.go1.24/src/net/mail/message.go#L325
				if strings.ContainsAny(v, "\"#$%&'(),.:;<>@[]^`{|}~") {
					v = mime.BEncoding.Encode("UTF-8", v)
				} else {
					v = mime.QEncoding.Encode("UTF-8", v)
				}
