The commit history of most projects I’ve worked on was simply not legible. They were a homogeneus set of meaningless stuff. Mainly short messages like "Fix the test" and auto generated "Merge branch fix/4839 [...]" texts. You could find some expressive messages, but looking for them was tedious. I think not taking care of a shared git log is not nice, and basically a bad practice. The log is a relevant tool and should be easy to use.
