I just don't have the same desire for respect the way I see it thrown around in other opinions. Respect in terms of "don't change things" has not been a lot of my Trek experience. Maybe that's colored my opinion but I'm not a huge fan of never changing and calling that respectful.
Where this didn't work, for me, was in regard to TOS. They spent 50 years telling fans, this is what this time period in the 23rd century looked like. From TMP (with the 1701 pictured) all the way to "In a Mirror, Darkly". Much of the merchandising continues to play to that angle because of the continued popularity of TOS.
I tend to think that a lot of TNG fans wouldn't have been very excited to see the 1701-D if it didn't look like the ship that they grew up with.
