Speaking of not being able to change it after the release, am I right to 
assume that this feature's main target is completing-read and not 
completion-at-point-functions?

Nobody proposed a patch for Company, and I'm not sure how to handle such 
non-semantic affixations in there (icons generally require more care 
since they often take up more than single character width).

Speaking of it's used in help--symbol-completion-table-affixation, we 
have recently added a related feature called 'kind' in Company which 
assigns each completion a icon (using a user-customizable mapping and/or 
algorithm).

You can see its integration in elisp-completion-at-point (the 
:company-kind attributes).
