You know what does not give me confidence? Updating software, but whats that, its still printing the same build date? Of course hours later tens of files deep I found out some reproducability goof just hardcoded it. So far, reproducible builds are heavy on the former, zero on these bugs you mention and zero on supply chain attacks. Some of these supposed use cases make no sense. You update the compiler. Oh no, all the code is different? Enjoy the 16h deep dive to realize someone tweaked code generation based on the cycle times given on page 7893 of the Intel x64 architecture reference manual.
