In preliminary results to the State of CSS 2024 survey, View Transitions came up as the 5th most common answer to the question "Are there any existing CSS features that you have difficulties using (or avoid altogether) because of lack of support, or differences between browsers?".

(can't share a link yet as these are preliminary results)

This is probably something more like https://wpt.fyi/results/css/css-view-transitions?label=master&label=experimental&aligned&q=types; whether we want to include everything in /css/css-view-transitions/navigation probably should be tied to #771.
