I understand support for Jaunty ended Oct 2010, so I presume it isn't even getting security updates. Thus "Jaunty will probably not be updated [to 2.6.37] by Canonical" would be something of an understatement. This does lead me to wonder why the kernel folk would care about Jaunty. I guess some people still run some legacy applications in a Jaunty chroot. And of-course there are some distributions even older than Jaunty that are still supported (e.g. Hardy).
