Benedict commented on CASSANDRA-7582:
-------------------------------------

I am less adamant about CfId checks as I am about failing on commit log checksum/mutation replay failures. I could just about live with (2), but naturally we will get better coverage by enabling this with all users. We don't know what bugs we might catch with it. So, I would prefer one of:

1) Start remembering old cfids in 2.1.1 along with this feature, so we can start complaining immediately; or
2) For now simply assert on non-CfId errors (i.e. make that opt-in rather than opt-out), introduce CfId recording at some point and make it opt-out at some point after
