Sylvain Lebresne commented on CASSANDRA-9402:
---------------------------------------------

bq. But I would still strongly prefer them to be off by default, at least until 
4.0.

I don't have strong feeling and I'm fine with not defaulting them on for 3.0, 
though if we get more confident about this before 4.0, I don't think we should 
feel obliged to wait for a major version to make the on by default.

Anyway, just wanted to make sure we at least don't call them experimental 
anymore for 3.0. It's ok to say we prefer having it opt-in for now because 
we're not entirely confident on our protections and you should assert the risk 
for yourself, but "expiremental" sounds like "don't use it in production it 
probably doesn't work".
