The problem is that this just doesn't work in practice. The LTS distros like RHEL are full of new bugs introduced by people who have to handle backports for dozens or sometimes hundreds of packages at the same time and who are just not very familiar with the way the code base works. Backports are new versions, just badly tested new versions.

I guess my experience differs -- I've been using Debian and Ubuntu stable distros for a couple of decades and can't remember running into a bug that was introduced by a stable/security bugfix update.

Some of this may depend on how long the distro promises to stay stable. The longer the stability promise, the more divergence there can be between the "stable" and current versions of the software and the harder backports get. That's going to put a practical limit on the length of any stability guarantee, presumably related to how well key upstream projects support older versions. A distribution that tries to handle its own kernel backports beyond what's supported by official LTS versions is setting itself up for problems.
