A processor cycle counter is helpful when mounting a timing attack but my 
museum pieces don't suffer from that problem.

Also, they are and always were immune from spectre, meltdown etc.

You misrepresent those secure hardware designs as being problematic, just 
because of some bad advice on some random blogs about RNG API usage.

Your insecure museum pieces are the real problem, not my secure ones.
