any movement on fixing the breakage of logback MDC with CompletableFutures?

I wanted to revisit the fact that MDC of logback broke in java's
CompletableFuture while it works just fine with scala twitter Future
because of their Local.scala class that acts like a ThreadLocal BUT for
Futures transferring context.

There is basically no way to fix it except by threading in some sort of into the CompletableFutures which would rock.

thanks for any info there,  (I would rather not switch this whole project
to scala and having the MDC in logback broken is extremely annoying)
