LDP or MPLS LSPs require hop by hop label swapping (directly connected or over say IP tunnels). So labels in LDP are always locally significant. SR-MPLS implies globally (domain wide) label significance. Index in the IGP extensions is there just to relax requirement to use the same block on all nodes - so the block does not need to be continuous in an SR domain. It is recommended by Cisco but not required by standard.
