This was reported in T90026 for attributes, but was also true for: - UVMaps - Vertex Colors - Sculpt Vertex Colors - Face Maps For Vertex groups and Shapekeys this was already done (in that their remove poll would check if there is a vertex group or shapekey to begin with), now make this consistent across all mentioned types. Thx @vvv for the initial patch (where this was done for attributes only) ref T90026 Reviewed By: HooglyBoogly Maniphest Tasks: T90026 Differential Revision: https://developer.blender.org/D11990
