Are there any efforts to make this feature a standard of some kind, maybe in HTML Living Standard?
I'm asking because it would be nice to get the same behavior in Safari where Cross-Domain communication with iframe doesn't work even for a subdomain (which works with storage partitioning in Chrome).
I'm asking this as a maintainer for a library sysend.js.
