Blender displacement modifier with procedural textures

Blender is possible to create a lot of good stuff with displacement node in Shader editor , but displacements are needed some times for game export purposes , animation physics , for production purposes and so on , which we can NOT do it procedural in blender ,we have to bake displacement texture and apply it on the mesh , which will only work with that mesh itself (not other meshes and a lot time consuming ) ,this is a huge disadvantage with blender , which can be fixed with an addon plugin or script .
