@feld Yeah. It should be easy enough to say, if you access this domain, auto open in container w/o the need to do the BS to "create" a container for that site. e.g. auto containerize this site. Though it is complicated by some stupid crazy SAML/SSO redirects that some sites do.
This would also apply to iframes, where if it attempted to access a site in an iframe, it'd deny the site, and open a new window for that site.
