Frankly, there's no way any arch venue at the time would have done anything beyond rejecting it with "caches make RSA fast, what's the problem?"

Security wasn't something CPU designers paid much attention to, and cryptography wasn't something they were even particularly aware of. Even seven years ago, when an Intel VP was giving a talk at re:Invent about "processor technologies for improving security in virtual machines", my question to him about cache collision side channel attacks was met with "what's a side channel attack?"
