I can see why a CA might want this to make it easier to get insurance,
as the liability is not unlimited. But the $100,000 figure in particular
seems low to me. In fact, as does the $2,000 per subscriber. If someone
has suffered significant harm, why should they not be able to claim more
than $2,000?

I'd like to see figures like:

Per-subscriber: $50,000
Per-cert: $1M
Per-incident: $5M

This still leaves the same per-incident cap, and so the same theoretical

EV is supposed to be a solid, validated cert. In 10 years we have,
AFAIK, had no confirmed cases of misissuance. The amounts available
should reflect CAs' confidence in the vetting.
