Is there any reason for "grounded alias" to "Grounded" transition not being "inertialization" for "blend logic" in AB_Als_Locomotion?

I want to set it to "inertialization" to solve some blending problem from "climbing" to "grounded" but worrying about break potential design.

I'm not exactly sure about the reason, the original plugin does not use inertialization either, I think there is simply no need for it.
For your case, I would just add separate transitions from new states to "Grounded", so that you don't have to change existing transitions.
