I don't think I'm obligated to support every trivial suggestion with a 
patch and a benchmark.

Or explain, from various POVs, why removing the sorting step "because 
it's expensive" is faulty reasoning.

Or why the grouping approach in icomplete mode should match what the 
default UI does and what other completion UIs (from which the grouping 
feature was extracted) do as well.

Whatever, do what you like. I'm out of this thread.
