It would be very helpful to server hosting to have an option in spigot.yml that prevents plugins with incompatible API's from loading (as defined in "api-version" in plugin.yml).

This would eliminate tons of issues with people that don't understand how plugins work or think that because the 2 year-old plugin loaded it must be working. They just install any old plugin without checking compatibility, and then bitch and moan when the plugin doesn't work properly and/or their server crashes.

Of course this means that plugin developers will need to keep the api-version in plugin.yml properly formatted and up to date.
