Sylvain Lebresne resolved CASSANDRA-10425.
------------------------------------------
    Resolution: Won't Fix

I understand the problem you are trying to solve, which is to help user not being stuck on outdated defaults (for their current hardware), but both me and at least [~iamaleksey] and [~JoshuaMcKenzie] (from an offline conversation) agree that auto-tuning feels like the wrong approach to it, and you seem to at least partly agree on that part (if I don't badly misinterpret your comment), so I'm gonna close that ticket if you don't mind as I think CASSANRA-11006 is a more open ticket for the actual problem.

> 1) Make GC modular within cassandra-env
> 2) For systems with 32GB or less of ram, use the classic CMS with the established default settings.
> 3) For systems with 48GB or more of ram, use 1/2 or up to 32GB of heap with G1, whichever is lower.
