So, both perl and python do not allow "deep nesting" of assignments.
For example:
d = { "a" : { } }
d["a"]["a1"]["a2"] = 42
Traceback (most recent call last):

Not sure I understand what you mean. In Perl you'd do
$ perl -e '%d = (a => {}); $d{a}{a1}{a2} = 42; print $d{a}{a1}{a2}'
42
which looks pretty much like what's proposed.
Indeed, I mentioned recently that perl auto-vivifies intermediate paths
like this.
But we don't do that in jsonb_set, as was discussed back in May, and as
JS doesn't either I think that decision is sound.
