Next release will be kernel 4.19 or 5.4 only, and the respective targets are still at 4.9. So, they haven't been included in 19.07 (4.14 only) and won't be included in future releases unless someone updates them. At the moment, it looks like nobody will update them.

So, we plan to remove these targets now, as they are effectively unmaintained. Those who still want to use them can have the 4.9 version in 18.06 stable branch until that one is EOL.

In both cases, updating or removing the targets, there will be no need to keep kernel support if no targets are left. Thus, we can save time for maintaining that kernel version.

Best
