I myself am not at liberty to move up to PHP7, due to laziness. I have inherited, in some cases, 5-8 years worth of accumulated legacy PHP5 code that I have neither the time nor motivation to audit/rewrite for the occasional line that might not sit well with PHP7. For new projects, I'd never choose PHP over full-stack JS or C#.NET - still, I think others would definitely benefit from the video you proposed, and if you should make it, I'd certainly pass it around the subset of my developer friends who like PHP.
