I don't think the cost is large, but someone needs to do the writing.
Emacs was never designed to display completions this way, so it's not
surprising these mechanisms weren't implemented until now.

Basically, remove lines one by one until it fits.
We could write a similar function to do what you want, but please note
that such a function will not understand the semantics of the text, so
it could suggest truncating it at some place which makes no sense. If
the caller would like a smarter 'service", we will have to come up
with some method of telling the function where it makes sense to
truncate the text.
