I've stated the same.

Yes, for me it's more a matter of reverting that change ;-)

I thought jcl-over-slf4j (or so) is used for that.

My main question stays: What does SLF4J offer that we have to use now for
CC? The last time I've checked (well, it must have been CC 1.3 or so),
logging was used only in one or two places at all anyway.

And Rahul's argument about some consistency between the commons component is
also valid, especially now with CC depending (optionally) on VFS ...
