Asserts and logging are two entirely different things. For asserts 
you often get messages like "assert failed: x > 0". This doesn't 
provide nearly enough information to locate the problem so people 
tack on other stuff like the file and line number. But for logging 
all you're really interested in is the text; you don't care where it 
came from. At least, that's been my experience...

Why complicate the design for a feature that very few people are 
likely to use? And if they do want it they can use the __LINE__ macro 
themselves.
