i would like to see in use the plugin called Plugman it allows u to reload byt force some plugins plus load in plugins without restarting the server
https://www.spigotmc.org/resources/plugman-improved.88135/
It would be nice to have a feature like this, but plugman isn't really the correct option.
If I remember correctly, plugman also alllws you to disable plugins. Being able to disable core plugins like the cubedcraft plugin doesn’t seem like a great idea. So I highly doubt it will get added
u could make it so if the plugin get disabled the server restarts or something along this lines thefore patching it
