Calling that a missed opportunity is a subjective perspective about the latest developments in KernelCI. The system implementation is one level less important than the actual kernel community engagement the project can generate. If one asks people around, the lack of community engagement with KernelCI is evident. However, after the recent leadership change in the project there is a growing effort to bring the kernel community closer to the KernelCI project with a renewed focus on high quality test results, clean regression reporting, among other things. Then, with an increased number of community members involved, we will have the necessary feedback (and funding!) to evolve the KernelCI infrastructure and technology to new levels. Otherwise, envisioning something that can solve *all* community testing needs would never be anything more than a fantasy in people's heads. - Gus -- Gustavo Padovan Kernel Lead Collabora Ltd.
