RL to split off a separate paper (#872) and rebase this paper on top of it

Polls taken for guidance:

POLL: Should we remove system_executor?

SF	F	N	A	SA
3	1	0	1	2

POLL: Are we interested in adding a scoped system_context which ensures all work submitted thereto has finished before its lifetime ends?

poll abandoned, need to come back with a concrete example

POLL: Should we look more into Thomas’ shutdown sequencing (created before main, destroyed after main) (and remove stop & join)?

SF	F	N	A	SA
2	2	2	1	0

POLL: We should be able to invoke an initiating function without an executor (including an I/O executor implied by the arguments)?

SF	F	N	A	SA
0	0	0	6	1
