I disagree with this, there are tons of addons that would tear Minehut to smithereens. If we had every single skript addon at our disposal, well, here's a list of bad things.
Reqn: Players would have access to the Private API and could give themselves ranks
Skript-mirror: Players can write pretty much any java plugin, this addon will never be added for the same reason you can't upload custom plugins.
Skungee: Players have access to the Minehut bungeecord, allowing you to kick, gain player ips, delete servers?, broadcast across all servers, pretty much shut down Minehut, etc.
SkUtilities: Players can edit directories and files, allowing for them to upload custom plugins, change paper.yml, change server.properties, etc
SkEmail: Disastrous email spam bots
skript-yaml: Players can edit .yml files, this also allows them to write lines in files and make directories because when you load a yml file, if that yml file doesn't exist, directories and files that dont exist will be created. People can also write lines because they can create yml values with whatever name, not gonna go into detail.
There are many addons that would be catastrophic to Minehut, I hardly listed any of them. The Minehut community has such a creative mindset that Minehut would be done for if they added all addons.
