ProtectHorses option in config no longer applies to non-horse mounts.

1.11 version split mounts into separate entities, they used to be variations of Horse entity. This causes donkeys, mules, skeleton horses and llamas to require container trust and ignore "ProtectHorses: false" value in the config.
I use ZHorse plugin to keep horses safe and this problem makes it unable for people to mount their own horses if they happened to dismount on someone else's claim.

Yea, I'm currently overhauling the plugin (and likely will have only basic, perhaps configurable protection of such entities), but if you want to PR a fix feel free to do so.
