You are right about that. As things stand now the 
annotation/affixation-function only work well for the default 
completions buffer and the vertical completion UIs. The 
completion-at-point popups are very different from that, so it is only 
fair if they try to invent their own metadata functions as you are doing 
in Company with `company-kind` etc.

However I am a bit critical with regards to the "semantic information". 
As far as I understood you use some icon names for that, but this 
restricts the purpose of the annotations. Maybe it would be sufficient 
to use a more crude solution, where you only specify that the 
annotations/affixations must be sufficiently short in order to display 
well in the popups, without going the full way to the semantic kinds.
