Block users in specific domains from joining ONLY webinars

Currently Zoom has a setting called: "Block users in specific domains from joining meetings and webinars".

I believe this will be the solution for many of the discussions I've seen here about notetakers joining webinars. For our specific case, this setting is be all end all, for both meetings and webinars. 

Is it possible to split these? I have already submitted the feedback to Zoom, but wanted to see if anyone knows anything here?

PS: I do not want to require authentications (this causes issues for some of our users) or require CAPTCHAs. The waiting room can help if people join on time, but what happens when they come in late? Do we have to be policing the webinar? 

Please advise!
