> Denial of service (or access) is one of several possible security threats. Unauthorised access, content modification or deletion, impersonation, and several other categories of security policy violations are also fairly typical.

Most of the cases of people losing access to their Google account that I've seen are not ones which would could feasibly be induced by a dedicated attacker unless they already had access to your account in the first place.

That may be a part of your personal threat model and also your decision-making, but from Google's perspective, that's not a security issue.

Unusual access patterns or attempts may provoke lockouts.
