New kernel feature and new supported hardware would be the only reason
for me to upgrade. Personally that doesn't come that often. My
hardware configurations don't change that much. I make sure it's well
supported, not just recently. When one buys a non supported hardware,
one should know the path chosen won't be the easiest.

For vanilla kernels, yes.

Because they want to ensure maximum stability. That's what users are
(sometimes) paying for.

And second 90% of the security issues will not affect the majority of
the home users (because they are restricted to a particular area of
the kernel not affecting the user, or because they already require
access on the machine to be exploitable). You will have much more
risks using a box with an unpatched php or apache than with an
unpached kernel, or without a proper firewall configuration.

That only happens for out ot tree modules, which shouldn't be really
out of tree in the first place. That's the issue. If they are out of
tree, it's for a reason. Either they cannot be in tree, or they are
not stable enough.

There you see the issue.
