Wow! This is all very exciting! And yet borderline terrifying. Let’s all try to remember that the colour of Mace Windu’s lightsaber, renaming Snoke “Plaguis”, and removing “Darth” from other Sith’s names aren’t continuity issues whatsoever. They are personal preferences, and the only way a group this size is going to come remotely close to a consensus will be if we stick to issues that specifically affect continuity. For example, the ST doesn’t really consist of any continuity issues at this point. Especially since 9 isn’t even out yet. While it sucks that the background of the Resistance and the First Order isn’t covered extensively in the films, their existence makes sense and doesn’t contradict anything other than people’s expectations.
I think this is a really good point - those things you list aren’t continuity issues. They may raise the odd question, but they are not ‘broken’. Let’s try to always keep that in mind, when judging changes.
