I think the biggest problem is that we know what the Trek universe should look like at this point in time, thanks to The Cage and The Menagerie.
STD is so out of place in comparison.
What is concerning is that they are using this 'Prime Timeline' label just as a marketing tool to sell the series to the fans, but really they want to go their own direction with it.
IMO, either set this series in a time where it would NOT conflict with existing Trek canon (like I suggested), OR it should be a reboot in it's own universe.
