[IPython-dev] Execution semantics and how to set them

I'm a language kernel author and I'm looking at the execution semantics
document[^1] where I see a reference to the "single" execution mode.
It says that the code
for i in range(10):
running in "single" mode would display 10 lines.
I looked through the IPython source and I see that the execution
semantics are set as an argument for `run_ast_nodes`[^2], but I see no
way that the given for-loop would give multiple outputs unless the
`interactivity` parameter is set to `last` or `all`.
Is there a way to activate this execution mode through a front-end and
pass that information to the back-end using the messaging protocol?
Or should I just implement the logic at the end of the document ("The
code field is split into individual blocks...") in my language back-end?
