Sure it's not beautiful, but it's an improvement to annotation-function.
If affixation-function were a function of a single completion, it would
be fine.  For a hint at a good design, look at the language server
protocol.  It returns a large list of completions, and then you can
"resolve" a completion to get many more of its properties.  So
resolution-function is an option.

If you prefer to see it that way, I have no objection, though I prefer
to think of backend and frontend simply (i.e. your C doesn't match
anything here very accurately).
