I would tend to think a high number of commits is a sign of activity and judging by the small number of developers, it shows they are dedicated to OpenBSD.

high number of commits can be one indicator of "goodness"

but consider an unsolvable problem that tempts developers, yet stumps them at the same time. they could all commit a solution thinking it's the right one, yet nobody actually solves a problem.

not saying this about BSD ... obviously, but: high number of commits is not a very good metric besides indicating that people are committing.

That, or a sign of bloat.

But, to be fair, everything is a sign of bloat.
