Actually we must map the concepts because ucm is designed for abstract the complicated kcontrol. In my mind, if we use ucm in pa, the original profile configuration files and mixer configuration files will be replaced by ucm configuration files.

Removing the original profile configuration files might be possible in an embedded scenario, but for all hundreds of different snd-hda-intel/AC'97/etc configurations out there, writing UCM configurations to fit all of them is just not scalable. (If so, one would have to write an auto-UCM tool that autogenerates UCM profiles based on present hardware.)

Yes, writing UCM files for PCs which have reasonably regular and discoverable audio is silly - if UCM is used at all on most desktops it should be with automatically generated configuration.
