So the sailing ship Enterprise pictured was still in existence as of 1979? I never said that small changes were not appropriate, and also, rather than completely ignoring the previous statement about 22nd century transporters, Enterprise tried to re-interpret it. Every new film in a genre is not a reboot light. Rather if an effort is made to tie the new work to a previous one, but at the same time do a drastically different depiction it is a reboot. If an effort is made not to dismiss the previous work, its a reboot light.
In my first example, both movies are about soldiers on missions during the Vietnam war, that is the exact same tie in between TOS, TNG and ENT all are set on ships from Starfleet sent to explore the unknown. If you made two movies, one about the Enterprise during WWII and the other about the Enterprise today they wouldn't be considered "reboot-lights" of each other just because they're both set on ships named Enterprise during a war. And no that ship wasn't around but the theme of the displays went "Sailing/Colonial era", "Modern Naval era (ours)", "Birth of space travel", "Deep space travel (presumably could also be intrasolar), "Current (theirs)" so they took one of the many Colonial/early Enterprises, the existing naval in 79 Enterprise, the shuttle Enterprise, a filler ship and the TOS E.
the ships are according to Okuda's DVD text commentary, an 18th century frigate, the much decorated World War II carrier, the space shuttle prototype, an unseen ship which was actually an early Matt Jefferies design for the TV Enterprise and of course, the original configuration of the Enterprise from the original series
My mistake, it
was the WWII E and not the existing one. But as I've said I agree with you that the argument that ENT didn't happen/isn't canon because it's picture wasn't in TMP is a ridiculous one.

That's a "spin-off"
"Something that is imitative or derivative of an earlier work, product, or establishment; especially : a television show starring a character popular in a secondary role of an earlier show"
The problem is you keep getting your definitions mixed up, calling spin-offs reboots and re-imaginings. Look up reboot on Wiki and read up on BSG (new) and especially the Wonder Woman Comic series which has a great example of how reboots work. Shows about different people in different times doing different things within the same canon universe are not reboots, reboots are about the same people in a different canon.
