This all looks very interesting, thanks for doing this!

Re this patch, is there some way LIL and HUSH could coexist, with HUSH
then being the initial shell, and one could then enter a "lil shell"
with the command "lil", just as I can start a busybox shell from bash by
saying "busybox sh". That could make it a bit easier for playing around
with initially.

I have no idea how hard that is to do with Kconfig. Perhaps make LIL
selectable by itself, then have a hidden symbol LIL_SHELL which is
"default y if LIL && !HUSH_PARSER" or something like that.
