I think Daniel is referring to what happens if you set completions-group
to t and type e.g. C-x 8 RET ROMAN TAB TAB (without icomplete): you will
see two "sections" titled 'symbol' and 'ancient-symbol'.

Right now icomplete-vertical-mode does not make use of this information,
AFAICT (unlike e.g. Vertico).
