-- What happens when the cure is worse than the disease (some variants of Spectre), and we "have to" patch because otherwise we're "not secure against this scary sounding thing." It takes a lot of agency away from the IT department to make an informed decision about the appropriate mitigation and threat model, and turns it into a business requirement regardless of the trade-off - because brass "understands" Spectre, they don't understand CVE-1234
-- Or, theoretical exploits that aren't practical in the real world, but we spend a lot of effort or make tradeoffs to fix just because someone needs some material for their PhD.
-- What do you call it when we find another way to read RAM next year - RAMBleed2? I guess.
