Chances of compromise of, or supply chain attacks on, QubesOS developers

I see QubesOS has reproducible builds. The documentation also indicates that there are serious security mechanisms in place.

QubesOS doesn’t have full support for reproducible builds yet, only some parts can be built reproducible:
