I’m gonna go out on a limb here and suggest that nobody is suggesting that.“As I recall the albatross was a ship’s good luck until some idiot killed it... yes, I’ve read a poem... try not to faint.”
As long as there are karens gatekeeping, the 3I and Charted Space will be dead in a generation. I guess when Mongoose release their brand new setting for Traveller, the grogs will be left stranded like pond fish in a drought.
When the main gaming community look at Traveller and make assumptions that it's still 1977 and crack jokes about "failed survival roll in chargen" you know the grognards have had their say too long.
You want Traveller to be forgotten by 2027, 2037, 2047?
I also suspect that a majority of players want the 3I setting to both stay alive, and not get nuked/changed/retconned into unrecognizability (is that a word? It is now!)
However, and correct me if I’m wrong here, but there might be room for both? As I understand things, the Fifth Frontier War will not change the “core setting” of the Third Imperium/Charted Space. It will rather be an (optional) sub-setting within the main universe.
Every player and group can choose for themselves wether to advance the storyline or not, the same way each group can choose to be Pirates of Drinax, or not be Pirates of Drinax.
Other changes to the Charted Space setting could be handled the same way, with expansions that advance the timeline and changes things. Perhaps by the year 1205 every ship has collectors as standard?
The book/line/series Traveller - Third Imperium 1205 (working title!) could explore this and allow for multiple sourcebooks and adventures to be related within this sub-line.
