How complex it is to test all known issues against all current kernels?

A weekly report with some easy to understand graphs would probably convince more people to work on these bugs.

Time and cost, same as it would be to do it across all kernel versions, not just current ones. Theoretically could be done pretty simply via a CI/CD pipeline if someone wrote solid test cases for the issues found by the fuzzier.

Thats my point! Make this part of the kernel regression and also run it on the old kernels.
