Caleb Rackliffe commented on CASSANDRA-17212:
---------------------------------------------

100% agree about {{replica_filtering_protection}}. I don't think there's a 
single nesting strategy that will be most elegant for every feature. In the 
long term, I would like to see us move toward nesting, even if that has to 
happen incrementally and imperfectly. (It seems like we've at least gotten some 
consensus for this in the {{[DISCUSS] Nested YAML configs for new features}} 
thread on the dev list already.)

I won't push for blocking this or CASSANDRA-17188 on a comprehensive plan for 
changing the entire structure of {{cassandra.yaml}}, but let's at least take 
care with how we lay things out now in case they later might fall into the 
proposals we've sketched out 
[here|https://github.com/maedhroz/cassandra/commit/49e83c70eba3357978d1081ecf500bbbdee960d8]
 and 
[here|https://github.com/belliottsmith/cassandra/commits/CASSANDRA-15234-grouping-ideas].

[~benedict] Given the discussion we've already had on the dev list, perhaps the 
best course would be to retrofit our nesting proposals once CASSANDRA-15234 
merges and post them in a new Jira, then pursue discussion there.

Interactions w/ CASSANDRA-15234 should be easy enough to spot in review. (No 
units in new parameter names, etc.)
