Here are a couple of real scenarios you don't seem to have thought about.
A 32-bit kernel on a legacy (or even new) system in 2017 will still need
regular kernel updates (not "long term" un0maintained kernels)
in order to work with new USB devices, new 4KB+ sector hard drives,
newer generations of SSDs, etc..

It's (mostly) all about drivers.

Cheers
