 These are valuable questions for the broader web mapping standardization discussion.
 
+**Update (May 2026):** The HLA community has published a Community Group Report documenting **S-LaWA (Sandboxed LaWA)**, an implementation that addresses the security concerns noted above — DOM isolation via iframe sandboxing, explicit author control through `data-lawa-mode`, and message-based integration. See [HLA Community Report §7](https://svgmap.github.io/presentations/W3C_Maps4HTMLCG/HyperLayeringArchitectureCommunityReport.html#security-and-isolation).
