You're looking at the "old" approach to that feature, using 
annotation-function. I couldn't just remove it here because the default 
completion UI doesn't know to use :company-kind (elisp--company-kind's 
definition is below in the same file).

The approach above has worked okay-ish over the years (so it hopefully 
illustrates that the use of affixation-function in read-char-by-name is 
not essential), but has the same flaws that I already described, for the 
purpose of using it seriously to show icons/kinds/types in different 
commands and completion tables.

Until now it has only been used for Elisp, and only to indicate one 
specific kind, so it was less of a problem.
