- Prevent --no-indexes from being combined with --for-replica, since combining these options can only lead to heartbreak.
- In --for-replica mode, dump caches too. See discussion in T13336. It is probably "safe" to not dump these today, but fragile and not correct.
- Mark the "MarkupCache" table as having "Cache" persistence, not "Data" persistence (no need to back it up, since it can be fully regenerated from other datasources).
