Does possessing the most powerful warship stop mattering?

Given the proposed G3's expected advantage on entering service, when does having the most powerful ship become irrelevant?

The prestige attached to the claim is judged enduring. Arbitrary category scores are rejected as a useful way to present warship comparisons.

Claims to possess the biggest or most powerful ship are treated as a continuing source of prestige. That persistent appeal is distinguished from the usefulness of attaching arbitrary scores to ships. Requests to rate different categories out of five are rejected. No date or technological threshold is given at which the prestige claim would cease to matter.
