PHP Compatibility Errors

I ran the PHP Compatibility ruleset (https://github.com/PHPCompatibility/PHPCompatibilityWP) against the plugin code (version 2.6.20) and here are the results. I am wondering how critical these warnings/errors are as I plan an upgrade to PHP 7.4 and if any one of them plan to be addressed.
