I thought the idea with these was that we were deliberately testing the earliest patch version of each minor version, because we ran into issues in the past where 3.13.0 had a bug where 3.13.1 did not, so we had to make sure that our backports worked with both versions

Yes. The .0 versions are unfortunately not available on Ubuntu 26.04, these are the earliest version. On the other hand, the latest versions will not be available on Ubuntu 24.04 going forward, since that won't be updated.

I think it's not too hard to have a matrix that continues using the older Ubuntu versions for the patch releases that aren't available on the new Ubuntu runners? #822 does that, WDYT?
