Can we say something stronger about how showModalDialog might be removed in a future version?  (Also, please capitalize the "c" in Consider.)

Apple isn't going to like commenting on future plans.  Perhaps "It will likely be removed ..." ?

As you already mentioned on IRC, the value of these messages is questionable at best.

I don't think that users of enterprise software that likes showModalDialog would be a grateful audience for warnings they can't fix (OTOH, end users don't open Web Inspector anyway).

Another reason why showModalDialog would be hard to remove in foreseeable future is that Adobe installer on OS X uses it (not on the web, but from a WebView in a native application).

I don't think that WebKit should ever officially claim that something "is broken". Better wording is needed.

Oh, I wouldn't put it like that. I think it can help to slow down the addition of new websites using this.

Do you have a suggestion? I took this text from UIEvent.cpp

I don't think there is interest in pushing this feature request further.
