Jonathan Ellis commented on CASSANDRA-6434:
-------------------------------------------
I'd actually prefer to use actual-repair-time instead of gcgs approximation
even for non-incremental repair. The latter means you could cause
"reappearing" data if the approximation is too optimistic (which was what
Sankalp originally filed this ticket for; I've modified his description).

> Since the reason for gcgs is to ensure that we don't purge tombstones until
> every replica has been notified, it's redundant in a world where we're
> tracking repair times per sstable (and repairing frequentily), i.e., a world
> where we default to incremental repair a la CASSANDRA-5351.
