Super long-term kernel support

I expect that when this product gets 'rolled' out people will be wondering why they didn't choose kernel 6.2 because it would have been out years before.

For a lot of industrial/infrastructure software, the regulations require testing/certification/etc which can take up to 10 years before it is 'done'. All the tools that are used to build it and any tools with the OS have to be 'locked' down for this and remain that way until the hardware is finally turned off in 40 years. [I expect teams in Unisys and HP are still working on versions of OS's that were written before most of the team was born.] If the project started 2 years ago, they may have already started the paperwork process of 'locking all the nuts and bolts' for these certs. Moving to 4.14 or some other one would require it all to start over again.
