WebView makes use of this allowlist. We are hoping to include switches and features in our crash keys as users can enable these with an easily available developer UI. These crash keys follow a pattern of "switch-<index>" so it is impractical to indefinitely add a larger list of switch keys. Adding this matcher lets us rather add "switch-*".
