Except for the overlap with Before and After.
It would have been so cool if they just threw in some old crew who had died or completely new crew we had never had before...
They could have brought back Stadi.
Stuck her right between Tom and B'Elanna.
Sparks.
Voyager only began experiencing the changes in the timeline once they entered that region of space. I don't see how the erasure of a species or whatever could result in dead crew members like Stadi coming back, since her death had nothing to do with anything in Krenim space.
Um, no.
They first experienced the changes in season twos before and After but from revelations to genesis even if time played out completely the same for the first 5 billion years it was a different timeline to perhaps not a casual observer, but "matter" had been removed from existence from the beginning. Time is like Jenga. And we didn't see the first 200 years worth of changes Annorax made playing with Krenim space by by extension the rest of the universe. Voyager interacting with thousands of different krenim Empires and arriving with or without kes' forewarning for one reason or another and how that changes Janeways composition toward these people who killed her in another timeline she has been told about. You will notice that Janeway didn't know who the Krenim was this time around, this thousandth time around, who suddenly a little later knew who her 20th century ancestors were despite saying she didn't in futures end, and claiming that she had never met Barcaly in Pathfinder despite having an adventure with his hologram in projections.
For your position to be true.
There would have to be some barrier.
A dividing line barrier point of differentiation between naked time and altered time that people on the outside could look in and say "What the fuck is that? Fuck. We're next."
And the locals in surrounding space outside this barrier perhaps bubble (a temporal shield around "Krenim space" and the nieghbours they wanted to consume) would have to be complete bastards not to put up warning signs and danger buoys surrounding such a vicious region where dozens of planets are vanishing dozen after dozen and the empires of note are rising and falling without pause or integrity.
More so, that because every timeline plays out till dooms day, all the thousands and thousands of timelines that Annorax crafted, each one of the Voyagers from all of those time lines would all leave that "region" (and any ship really, or even planets whose orbit dips in and out back and forth over the division between naked and altered time.) intact and wondering why there are all these dopplegangers following them out of "Krenim" space.
Define region, because (reused sfx) the planet from Virtuoso seen in Voyagers 6th season was one of the worlds Annorax demolished.
So, no.
Time is a universal constant which flows like water at the speed of reality.
I once supposed that the ripples of Annoraxs weapon would be creating thousands of rings of causality for the next untold infinity years till till they all hit the rim of reality... Fuck. You know what could hem in Annorax's causality weapon? A barrier no one would notice? Because it's so fricking big and has always been there...
The Galactic Barrier.
