Lets go to the basics.
You partition tables for one of two -or the two of them - reasons next:
Condition #1- To help queries
Condition #2- To help purging
1- Your "partitioned" index is not providing more help than a normal b-tree index on the same column so, condition #1 is false.
2- Purging -as in truncate or drop - of "one" table partition would probably invalidate "all" the partitions of your "partitioned" index then your purge process is not getting any help from it so, condition #2 is false.
false/false means you don't do it.
