Git is a lot of things at once:

1. A tool to record development history - warts and all
2. A tool to create a logical sequence of changes
3. A tool to communicate intent and ideas to a maintainer

Meaningless messages like minor and . don't suit any of these roles - not even 1. Even when recording development history with all mistakes, you'd still need context when you look back at the history. Matklad is a well respected developer. I wonder why he's make such a bizarre claim.
