My old grognardy brain has to adapt
There is that
Here is the thing though. There are degrees of canon. For example, there is Canon-canon, the real sacred cows. A week in jumpspace, no FTL communications beyond that jump, and so on. The things that, without them, it simply would not
be Traveller/Charted Space/OTU.
Then there is another level of canon, the things that really should not change but are not completely, wholly, 100% inviolate. I'll come back to that.
Also, very occasionally, you might see something that makes you think 'yeah, that has to go'. Suspicious naming of worlds, for example, or the Droyne becoming a bit more equal opportunities. It goes against what has been written in the past, but I think most can agree that Traveller needs to be 'current' and that some things are worth slipping past.
Then there is 'experimental' canon. This is one of the uses of JTAS, a format where we can 'float' ideas, see how they are received, and either fully incorporate them or let them lie fallow (incidentally, this approach is not necessarily restricted to JTAS, and larger titles can fulfil that function - in a way, on a long enough timeline, they all do).
The Golden Rule is this for most aspects of canon: Unless it is Canon-canon, everything that has gone before remains canon... unless there is a better idea.
Put another way, Traveller cannot and should not be a fixed point that never moves. It needs to breathe, develop, and be a living universe. The OTU of the 2020's is going to be massively different from the OTU of the 1980's, and the OTU of the 2060's will be massively different again. Aside from Canon-canon, of course.
Put yet another way, Charted Space/the OTU
must be allowed to change, be tweaked, be experimented with if it is to remain vibrant. That is not to say we stamp around in army boots, but a constant exploration of the setting is at least as important as a constant exploration of rules mechanics.
This, incidentally, will go double as Traveller moves to other media - while a novel or even a comic might cleave close to the RPG, a video game or film might, by necessity, force some things to give way.
Just an interesting thought experiment, that last part
