PHP 7 support?

I ran the wpengine tool which test for PHP7 compatibility. https://wpengine.com/blog/php-7-compatibility-checker-plugin/ It returned these findings about contact form db. Do any of these matter? Do you have a plan to update for PHP 7?

As we see from your test log, you are using “Contact Form DB” plugin ( https://wordpress.org/extend/plugins/contact-form-7-to-database-extension/ , is currently missing on WordPress), that exports the Contact Form 7 plugin data. It is not our product. Our plugin is Contact Form to DB ( https://wordpress.org/plugins/contact-form-to-db/ ) that allows you to write the data of our Contact Form plugin to the database ( https://wordpress.org/plugins/contact-form-plugin/ ). You should contact Contact Form DB plugin developers.
