In https://bugs.webkit.org/show_bug.cgi?id=260684, we put support for this role behind a feature flag. Let's remove the flag and the feature entirely eventually if no complaints are made about it being missing.

Is this the same as bug 260641?
I posted more detail in https://bugs.webkit.org/show_bug.cgi?id=260641, but I think it's better to push other browsers to adopt this role rather than remove it. There's an important use-case for the text role.
