Mentioned back in 2016 by Viktor Kostik, in animation developement DayZ Dev Team uses "in-house, automated animation exporter which generates data that can be used in game" thats still not available for modders.
Making this tool available for modders will add more possibilities for creating custom, previously unseen animations from community to community.
As well as making these custom animations to be not dependent of "default character sizes", this will make disproportionate characters/infected/animals easier to create and add more customization possibilities to modders.
