 I think it's unnecessary (and maybe bad idea) to add a new tags to
 the high level part of the library. The high level tags have been
 introduced to support mount/fsck devices by LABEL= or UUID= tags
 (only this is reason why we have the new PARTUUID= tag there). I'd
 like to keep this layer as minimal as possible (due the problem with
 caching in blkid.tab file).
 
 If you need information about devices then use lsblk(8) rather than
 blkid(8).
