Not sure I understand. Grouping is a linear operation, isn't it? O(N).
Which is generally cheaper than the sorting step that came before.

Could be it misses information.
OTOH, if you split completions belonging to the same group apart, you
can end up with a list where there as as many group headers, as there
completions (in the extreme case).
What behavior does (setq completions-group t) have? It affects the
default UI, IIUC.
