So the write up on the Spyrers in the Book of Desolation does make a few very significant changes to the story, background, and setting.
Specifically that the Spyrer suits are no longer alien (Jokaero? Tau?) creations that are smuggled to Necromunda for the wealthiest elite. Instead, these learning rigs are built in-House by House Hellmawr (though the source of the better-than-Imperial-Military technology patterns isn't suggested at all here?), and are very much exclusively granted to a very few House Hellmawr individual nobles, and not to any of the other noble Houses.
The original N95 / N03 version of the setting had the Spyrer suits be amalgams of off-world technology (hinted at various times to be Tau or Jokaero in origin - though given the nature of the suits, Jokaero made more sense), and used in a "coming of age" ritual by a swath of nobles from all of the noble Houses of Necromunda.
This is a significant change, and it retroactively would invalidate a scattering of fiction from White Dwarf, Inferno! magazine, Citadel Journal, and various novels and short story collections.
