It's a remastering, not a reimagining. They are taking the correct stance in preserving the show how it was, first and foremost.
If they want to do an alternative version as a viewing option (with new effects, new ships, whatever), they can make that decision afterwards. In the meantime, I want to see the original work as it was made in the 80s/90s, with as much clarity as possible.
I'm just going to assume when the TOS blu-rays were announced, this place went up in flames.
