Kernel regression tracking, part 1

Isn't the information in this article evidence enough? Distro kernel people are independently tracking regressions. Wouldn't it be better if they could share data with each other, and with the maintainers who are also tracking regressions?

Whether maintainers are tracking regressions in their heads, in a text file, writing notes on a napkin, or however, they are doing it, just in a way that's inaccessible to others.
