> Currently, the node lifecycle event timeline among fragment instances is
> expressed in list format, without any form of summarization.
> Now, with the inclusion of aggregate metrics in the experimental profile in
> JSON format, it is possible to display them in a comprehensive format, which
> would help in skew analysis or other such cases.
