I suppose it would have been less impactful to have them say the crew was being decomissioned but not the ship.
At the time fans could have maybe rationalised (given there's so much that kinda is open to rationalisations) that just the crew was being stood down, and the ship would have been re-crewed and sent out with a new command crew but then Generations blew that out the water by having a totally new ship! Never mind though.
Regarding the corridors, again, none of this stuff makes a lot of sense if you stop and think about it - a Connie has in TFF identical corridors to the 'state of the art' Galaxy 90 years later, but then in the next film they are different, along with the bridge - so, yeah, each director just did a ship revamp to suit themselves.
As it turns out, Abrams did the same thing!
Actually we technically don't know anything about the fate of the ship after 6. In fact we can actually see logic for the decommissioning of the ship at the beginning of the movie during the briefing with the Star Fleet C&C during which it is stated, not in these exact same terms, that the peace between the Klingons and the Federation would almost certainly result in a draw down of force size. Dismantling of the space stations and starbases, mothballing of the star fleet, etc. Decommissioning is nothing more than taking the ship out of active service. What happens beyond that is kind of up in the air. Most people tend to think scrap yard, but in reality reserve fleet is also quite possible since a lot of ships go there before the scrap yard. A reserve fleet is really just a bunch of ships that are fully functional just they aren't armed, have probably minimal fuel on board and are either fully or partially decommissioned. In fact I think in the novel Sarek, that's kind of what happens. In addition to the adventure in the book, the ship is kind of in a partial decommissioned status to effect repairs before going inactive.
