Yes, there is a big update for Cookies and Content Security Policy coming that will solve the issue of having to set all the same settings to all of your sites in multisite. This is solved by a little checkbox in the network admin that tells the plugin to read all the settings from the main site. Smart huh?
Now: Since this is a big update. I’d really like if some people beta testing it. So; reach out in the comments, e-mail me or whatever and I’ll hook you up.
