To state the obvious,...
All of this half-this,/half-that labeling is the opposite of attracting or opening the series up to new viewers. I wonder if the producers even conscious of that or are running on autopilot.
it's a peculiar Star Trek in-group coding premised on the notion that a character's racial background tells you something interesting about them. That it should be the first thing we're told about them. That the character's appearance should be designed to make us curious about what basket we should sort them into - which is doubly funny, because most "alien" makeup design in Star Trek is so minimal and conservative that it has little potential to catch the attention or imagination of anyone who's not already into the franchise.
It's also a problematic, old-fashioned kind of storytelling shorthand that many people would call "racist" now if not for the good will that Trek has built up on so many fronts.
