Despite the Health Check & Troubleshooting plugin being all of 3 weeks old and made by the [WordPress.org](https://WordPress.org) community, using it to check what the “Highest supported PHP” is for a couple dozen plugins turned up “Could not be determined” for every single one of them except itself. Some of the plugins are very popular, so the odds of this happening are low. It must not be working.
Does anyone know of one that does (for 8.x)? Or maybe just a database of the information to be referenced manually?
