It does seem like the dagger would have been made recently by Ochi, doesn’t it? It may be easier to find one moment to state that somewhere rather than change several moments to make the blade seem older.
If the blade was made, say, fifteen years ago, then it would even make sense to keep the goonies moment in.
But why would he create a dagger with a shape resembling the death star wreck?
JJ/Terrio were saying in the documentary that they wanted an object the Sith cultists would pass to one another to guide them to Exegol. The problem is that the dagger doesn’t point them to Exegol, it only points them to the wayfinder - which can only be in one place at once. The stupid concept here is that these cultists are returning the wayfinder to the Death Star wreckage every time they come back and that Rey didn’t enter that room to find it empty - as in all likelihood it ought to be.
