+[UNSTABLE] Add a new `unstable_defaultShouldRevalidate` flag to various APIs to allow opt-ing out of standard revalidation behaviors.
+
+If active routes include a `shouldRevalidate` function, then your value will be passed as `defaultShouldRevalidate` in those function so that the route always has the final revalidation determination.
+
+- `<Form method="post" unstable_defaultShouldRevalidate={false}>`
+- `submit(data, { method: "post", unstable_defaultShouldRevalidate: false })`
+- `<fetcher.Form method="post" unstable_defaultShouldRevalidate={false}>`
+- `fetcher.submit(data, { method: "post", unstable_defaultShouldRevalidate: false })`
+
+This is also available on non-submission APIs that may trigger revalidations due to changing search params:
+
+- `<Link to="/" unstable_defaultShouldRevalidate={false}>`
+- `navigate("/?foo=bar", { unstable_defaultShouldRevalidate: false })`
+- `setSearchParams(params, { unstable_defaultShouldRevalidate: false })`
