The Problem

I would like to provide spawn eggs to players under certain circumstances, however I only want them to be able to spawn a single mob from it. Unfortunately players are able to use a spawn egg on a spawner in order to get an unlimited number of that mob spawning.

A Solution

A modify-spawner flag could be added. When set to deny, it would be impossible to use a spawn egg on a spawner.

Alternatives

Only alternative I can find is to not have spawn eggs in the world at all. We can't individually protect each spawner with use deny, as we have no idea where spawners will generate. We need a tag we can apply to global.

Anything Else?
