A more nuanced handling is certainly possible: we can keep Diagnostic-based old behavior on nightly only.

It adds to the code complexity but is worth considering imo for cleaner diagnostics output.

Extra complication:

1. nightly diagnostics is not currently tested
2. #[allow(deprecated)] will not suppress custom warnings so we need to enable other ways to suppress these warnings. A more invasive and perhaps more granular way is to invent something like HtmlAttribute that expects something like #[yew_style::pre-0.24] inside html!. A less invasive way is to invent a new macro like html_pre_024!{} which turns off style recommendations.
