• The WG's request for this TAG review: https://github.com/whatwg/html/issues/11743
• Previous early design review, if any: n/a
• An introduction to the feature, aimed at unfamiliar audiences: This feature enhances performance by discarding duplicate navigation requests that occur within a brief (3 second) window, preventing the unnecessary cancellation of ongoing navigations.
• A description of the problems that end-users were facing before this proposal: Accidental duplicate actions, such as rapid double-clicking, currently trigger the cancellation of progressing navigations, resulting in redundant network connection and delays.
• Alternatives considered: Alternatives such as navigation transformation or pipe transfer were rejected due to complexity (see TPAC 2025 presentation).
• Examples of how to use the proposal to solve the end-users' problems: This is a transparent browser optimization.
• What do the end-users experience with this proposal: Users experience faster and smoother page loads because their initial navigation intent is preserved even if they accidentally click a link multiple times.
• User research you did to validate the problem and/or design, if any: Chrome experimentation showed a decrease in navigations marked as exact duplicates, and a more significant reduction in the number of server responses that were sent but potentially never rendered. This also improves overall latency.
• Web Platform Tests:

The specification
