it is a big itch for my use case. Repair ends up streaming tens of gigabytes of data which has expired TTL and has been compacted away on some nodes but not yet on others. The wasted work is not nice plus it drives up the memory usage (for bloom filters, indexes, etc) of all nodes since there are many more rows to track than planned. Disabling the periodic repair lowered the per-node load by 100GB which was all dead data in my case.
What is the issue with your setup? Do you use TTLs or do you think its due to DeletedColumns? Was your intension to push the idea of removing localDeletionTime from DeletedColumn.updateDigest ?
