ENUM partitioning options?

I'm trying to work around the ENUM partition bug (

I have a table that I'd like to partition on ENUM. Due to some dependencies, I can't easily convert the ENUM to any other type (TINYINT, etc.).

Is there any way to partition (even hackishly) on the ENUM so pruning works?

PARTITION BY LIST(ENUM COLUMN) fails with "The PARTITION function returns the wrong type"

PARTITON BY KEY(ENUM) claims to work, but it doesn't look like pruning ever happens ("EXPLAIN PARTITIONS" shows all partitions are always selected)

Are there any workarounds? CAST is no longer allowed -- does ABS(ENUM COLUMN) work for ENUM partitioning?
