Jessie might be nice from testing perspective, but only when it's not making 
life too hard for moving on. Practically, it plays no role in the field, simply 
because everyone started on Stretch as Isar was not usable at the time jessie 
was the latest version.

Not quite: Kernel and a set of Debian core packages (we are still shaping the 
latter set) will be maintained for 10 (ten) years. There will soon be an 
official Isar layer encoding that package set (it's currently only in 
https://gitlab.com/cip-playground/isar-cip-core).
