[_delirium]

I only find blame-type tools useful for discovering either recent context, or context of rarely-touched code. They typically only easily show you the most recent change to a line of code, though you can sometimes dig through older changes in a kind of per-line commit history. So older changes get more and more buried under an accretion of more recent ones. To find the commit message discussing a performance hack from 8 years ago, you'd have to wade through all the more recent commits that also touched those lines of code (refactoring, fixing unrelated bugs, fixing library bitrot, etc.). I'd rather that important context stay right there in the code, not get buried among hundreds or thousands of other commits.
