Redis What the sence of build-id of redis?

The build id of other opensource software generally only including machine code and time stamp, but git infomation added in redis. Is build id for traceability only ? Or something else ?

@LockLi the idea is to have each specific binary of Redis having a fingerprint, so for instance if we see two crashes with the same build ID, we can be sure the same binary generated them.
