If I am not wrong, for system tables expect meta we still share logs with user
regions, so even if we have some logic to assign system tables first, we still
need wait log splitting done and we can not guarantee logs of system tables are
split first. So there may be a blocking task that we should make multi-log
feature having priority and write entries of system table in the highest
priority logs. Thanks.

This is an umbrella for working out our long term plan around how we handle WAL
prioritization and recovery.
