If you're 100% sure that nothing will break, go for the slf4j-based
approach.

100% certainty is difficult :-)

How about this:

1) Implement new MDC functionality only for Slf4j
+0

2) Switch the default logging to go through Slf4j (with log4j backend), but keep
existing Log4j functionality
+1

3) After a while, cleanup and remove the log4j native logging
-1 deprecate first and then remove later. Given my recent Scala 2.7 to 2.8 porting experience, I now appreciate the significance of @deprecated() even more :)


Depending on the time frame, we could postpone 2)+3) to sometime after M2
