Thanks, I see it.

6 months, not very long in Emacs release terms. But indeed you're right
that it wasn't last week..

Either that, or it could return a list instead of a string, and then the
list would be interpreted as "affixation function" results.

Yes, but users love to foot-shoot and who is going to enforce that?
Your icomplete patch doesn't, for example. Whereas if it were a unary
function of a completion string, the hazard wouldn't exist.
In the meantime, I've read some of
https://lists.gnu.org/archive/html/emacs-devel/2020-11/msg00613.html
and it seems one purported advantage of having `affixation-function` see
all the candidates is to be able to do layout decisions since it knows
the longest and shortest candidate. At least this is what I read from
https://lists.gnu.org/archive/html/emacs-devel/2020-11/msg01009.html
But I don't understand why these decision should be done in the data
backend. The backedn should only annotate a completion with a possible
_hint_ on how to layout ("prefix" and "suffix" are hints). It's the
frontend, who is who knows what to display and where, who should be
responsible for the layout.

That's valuable information. Let's wait for Juri and Stefan on this.
