Unofficial PocketMine builds are not supported. It is their own fault to add backwards-incompatible changes to their codebase, and we are not responsible for cleaning their mess for them.
Doing this will either remove a feature in Specter, or that we would have to add extra code to check if that method exists to all of our distributions. Both of these are bad.
