It's an example of a user trying to write a completion table (to be 
consumed by company-capf, as they usually are) with sorting logic and 
tripping over the flex style overriding it.

The problem is more or less understood: flex overriding the sorting 
logic even if it's defined in the table.

There is no point in me retelling the discussion. It is itself a piece 
of evidence for the problem existing. Maybe not categorical evidence, 
but evidence nevertheless.

You should read it (the last few messages will suffice).

flex is popular enough. People use it. I end up having to diagnose 
people's problems.

Having many similar-but-slightly-different styles available is unlikely 
to reduce my support burdens.
