Backporting packages is a time-consuming process that actually requires skill. It is insane to expect people to do that for free on a volunteer basis because it makes your situation easier, especially as backporting gets harder the longer you go. RHEL offers 10 years, it costs money, that's your option. Or you pay for the staff to monitor and backport to your particular distro and foot the bill.
It's also maddening to present the issue as "our time is expensive and your time is free". If your field is unable to commit any work at all to updates, fine. UBI Micro is as small as its gonna get and moves everything difficult to the host. That could conceivably run for 15 years if you are careful with how you build it.
