Well no one says my assertion is false, so it is probably true.

Going further, what would be the steps to migrate from STC to LCS ? Is there any precautions to take doing it using C*1.1.6 (like removing commit logs since drain is broken) ? 

Any insight or link on this procedure would be appreciated.

At least for our use case (reading slices from varyingly sized rows from 10-100k composite columns with counters and hundreds of writes/second) LCS has a nice ~75% lower read latency than Size Tiered. And compactions don't stop the world anymore.  Repairs do easily trigger a few hundred compactions though, but it's not that bad.
