I can't agree with this however, because I've never seen a post that stated anything like this.
I'd be willing to find a post or two, but it was so long ago, that it's probably burried under one of the thousands of "Archived Post" comments in the forums. You know, the result of Cryptic's botched "upgrade" of the forums a few years back.
But yes, it was stated (repeatedly) by both players and Cryptic devs alike, that any inaccuracies in the canon models, can be explained by it being built in 2409 (30 years post-Nemesis). I think CapnLogan was one of said commentators, and he was the ONLY Cryptic dev who actually worked on trying to fix some of the inaccuracies. Sadly, he left Cryptic to go work for Bungie. Since then, there has been little in the way of progress, of fixing said inaccuracies in the ships.
