I constantly get meshes with uvs,textures, morph targets etc that need to be adjusted and changed. The claim that there is a certain order to things is not how real world projects work. There are constant changes to models and uvs from Customers, Directors, Art Direction, TDs etc. I do this stuff for 15 years now. Redoing the uvs every time because they are completely broken by the symmerty object is simply not a good workflow. Not even talking about morph targets. But it currently is the C4D workflow.
Ok it may be hard. But strangely basically every modelling software out there can do it. Maya can , Max can, Blender can a bit, ZBrush can, 3D Coat can, etc...
Weren't there even coffee scripts from Cineversity that didi it?
