I think it's better to show the descriptions by default without an extra option. I suspect most people want to see them, or if they need them they won't know about obscure -v options.

The problem with this format is that it is not compatible, so it would break existing parsers that look at perf list output. That is why I ended up with the right side format.

I guess what could make sense is a quiet option to not print descriptions.
