Moving to PHP7 isn't as straightforward as I first thought it would be. Depending on their supported modules I can understand why they aren't on 7 yet since some of them haven't a stable release yet.

Also 2 Months ago at the WordPress community summit it was discussed how to upgrade safely the PHP version. That is also a huge challenge to be tackled. It's still on my plate to build some tools to check the quality of a plugin and which versions it works on
