Yep, and that fact makes me hopeful. However, it's not unusual for other companies who are not Jetbrains to implement undocumented APIs for internal use only, while exposing a different set publicly. Or even to bake some part of the plugin functionality into the core product that a plugin mostly serves as a "key" to unlock.
I'm sure this would be quickly found by anyone decompiling the plugin or otherwise investigating how it works if they did so, though.
