Yes, true.
Relatedly: any option other than (i) or (ii) or (iv) has a limitation: if
{ko'a poi broda} is a referring expression in itself, one might expect
{ro ko'a poi broda} to mean
(1) {ro da poi me ko'a poi broda},
but instead we have a separate rule which makes it
(2) {ro da poi me ko'a gi'e broda},
and (1) and (2) agree only in case (iv).
They almost agree in case (v), and I'm tempted to amend case (v)
to have it give {ro ko'a poi broda} meaning (1) rather than meaning (2).

Yes, this is definitely attractive in its simplicity. It's much looser
than restrictive relatives in english, though; if I point at some
assorted fruit and say {ti poi plise}, with (iii) there's no reason to
think that I'm referring to all the apples rather than only one.

Agreed.

Almost - but assuming we work with (iii), that doesn't get the idea that
*every* individual among ko'a which satisfies broda is a referent of
ko'a poi broda, as (iv) states.

Not the way I meant it. I meant it as a translation of the english
"those of ko'a which broda" - which is rather more specific than (iii),
which is more like "some of ko'a, that broda,". (v) was also an attempt
at translating that english phrase.
This just reminded me of [Chierchia98]; using his notation, (v) (with
error when there's no unique maximum) can be expressed:
{ko'a poi broda} ->
\iota { x | x <= ko'a /\ broda(x) }.
It seems a reasonable translation of english restricted relatives.
I just had a quick look at some semantics papers, and I have the
impression that this is indeed a standard way to handle them - but I'm
not confident I'm reading the literature right.

They look reasonable to me. Taking {lo broda poi brode} to be have the
same referents as {lo broda ku poi brode} would also be an option.

Yeah, I don't think that's really legitimate. Pretending that {ri} can
pick up the {da} at all (and actually I believe it just skips over it to
the previous sumti), I'd say the bracketed phrase there has an unbound
("donkey") variable, and we should either consider it an error or
universally quantify it out to give
{PA broda noi brode} -> {PA da poi broda zi'e noi brode}
-> {to da brode toi PA da poi broda} *
-> {to ro da brode toi PA da poi broda}
or, perhaps, remembering the domain of the variable and only universally
quantifying over that, giving
{to ro da poi broda brode toi PA da poi broda} ;
but that's a bit of a pain in practice, since the clause giving the
domain could itself mention unbound variables, and you have to recurse.
