I did some more digging, in the show the DMA was referenced as appearing more than 1000 light years away from where it had appeared. Discovery season 4 episode 5.

I tried to stay away from points that would be spoilers.

The technology had control over gravity and demonstrations of the environments it created on display.

You’re going to argue a device drawing energy directly from black holes is limited in its scope of creation?

The progenitor said it could create life, not replacements of what was. It also said the scale and speed were up to the one managing the process.

They could have easily replaced any of the species that were wiped out. Not trying to argue for exact copies of books family, only the life forms and planets.

Only 20 light years? Say that to the life forms that stopped existing.

Season five was written without propery continuity.

The show had amazing actors, beautiful graphics, and bad story writing.

All the damage from season four is ignored, except Book’s romance.

There were entire sectors of space that are voids because of the last season.

If they were to use the power, they could rebuild kweijan and all of the damage to planets and creatures in season four.
