rename UV of all or selected objects

If there is a function to name a specific mesh by a name, then why is there no function to rename selected meshes in order for the material intended for a group of objects to work, because the uv mesh is not always made in different uv spaces, if I have 100 objects with a single uv or I have to use the standard one named "UVMap" but then the material will be applied to all objects, even newly created ones, etc., or I select the objects I need and use the script;

import bpy

for obj in bpy.context.selected_objects : for uvmap in obj.data.uv_layers : uvmap.name = 'MY UV'

So that's the crux of the matter, you need the ability to rename UVMap. Covering this question with scripts is unacceptable!) The program is still considered completed.

In addition, you need not even just the function of renaming the map, but the correct work with layers - workers! collections! or layers! whatever you call it - the main thing is workers, but at the moment everything is disconnected, and the problem with UVMap confirms this!

Or I will explain it differently - If I created a collection, it should be not just a folder! - and the material, and the change in the shape, and the modifiers, and the names of the uv map - all this should be able to change and apply to all objects in the container and to each individually, if desired ... and this workflow is logical and generally accepted ... in the blender everything is just scattered !!!!
