Not to play the devil's advocate but... do we want old kernels hanging out that

Besides not encouraging people to update to new releases that mitigate
discovered CVE's, we'd also not pick up David Taht's excellent improvements in
Buffer Bloat.
I have to agree with this.
What would be the benefit for OpenWrt with having LTS kernels
supported for 6 years?
One aspect I could see is take for instance a device that is widely
popular amongst our user base as was TI's ar7 for instance a while back,
and for which we might have done a Linux 5.4, or 5.10 version at the
time but we do not wish to continue to maintain.
Being able to continue to deliver stable kernel updates in a stable
OpenWrt branch could be a good way for users to pick up their next xDSL
router since there are not so many out there that can actually run
OpenWrt compared to pure Wired/Wi-Fi for instance.
Backporting stuff is already hard with only 2 LTS versions supported in OpenWrt.
That argument I am sympathetic with, and the sheer amount of out of tree
patches we have in OpenWrt is not helping, in fact it definitively makes
it harder to regularly test, but still somehow we managed to do it.
Since we will merge stable updates eventually, the point would be that
instead of testing those that are already released, we could try to test
the release candidates and report back anything we find?
