Resource pack based keybinding

You know how datapacks are hosted on the server/client it's ran on, while connecting players can only receive resource packs? Well what if you met in the middle for keybinding and made it so resource packs can macro the /trigger command (and only /trigger to prevent cheating) so mapmakers can create custom keybinding for their datapacks. So if I assign a trigger to g in the resource pack, it will run /trigger g. This would make keybinding very accessible for datapack makers without having to figure out how to connect host and client through datapacks. Cuts out the middleman
