This would be perfect! We would see, what we need to address in our fleet (we are not using a distribution). But distributions would have something to build on, too. They might create a feedback path of this information from the systems of their users to the distribution. The basis for everything is that the information "you are using a mechanism, which will go away" is made available in a structured way.
It is important that the information cannot only be found by digging through masses of unstructured text in mailing lists, documentation, NEWS files, dmesg or other sources and then having to analyze in each individual case whether it is is relevant to you at all.
