Don't you mean "I *am* the maintainer of this area" ? I've always
assumed it means "as the maintainer I have a potential veto over
this code change and I am explicitly not exercising it even though
I may not have done a complete review and/or test"...

I think Andreas is the major exponent of the idea that "acked-by"
is stronger than "reviewed-by". Regardless, I think we should
standardise on what we mean by both tags. (Alas the kernel docs
are not entirely clear about acked-by, though the meaning of
reviewed-by is certainly clear.)
