That's a fair point, I just figured a Command would become part of a Lifeless' Spirit Web, possibly as part of their Identity. 'Would Commands be part of a Lifeless' Spirit Web?' Is probably a better question, because if it is, then it may open up the possibility of mucking about with Hemalurgic spikes. Or are Commands just inherently Breath/Investiture overlaid on top of the Lifeless? Do they not show up in the Spirit Web at all?
As an aside, from what you posted, along with
It seems as though Lifeless somewhat retain their original Identity (I'm probably treading ground others have covered on these forums here).
(Also sorry for posting the full quotes, I can't post links yet.)
