Yes and no, my experience with it is that it is trying to be a minimal Git format-compatible tool that conforms with the coding style and practices of the OpenBSD community, along with their style of development: patches onto mailing lists. It is likely the hope of its developers that it would be included into OpenBSD base at some point. So, true, the license is a part of it, but one part of many.
