1. Mike Minor and Joe Jennings never liked the design of the TOS Enterprise, especially the nacelles. To my knowledge, there wasn't any dislike about the Enterprise-D's design other than that we'd seen it for seven years.
Whilst I agree with the rest of your post, it's clear from the DVD commentary that Moore and Braga were very keen to get rid of the D, not liking various design elements, the families and claiming it was hard to film to look good IRRC other people involved in the show have made similar claims over the year, it's worth remembering that by the time you get to the films very few of the people involved in the D's design are still involved with Trek, so it's perhaps unsurprising that a lot of the thinking behind various parts of it had gotten a bit lost
