If the team decides for text parse, is it okay to use additional property in options (like allowHtmlParse) to skip unnecessary RegEx checks for better perf?

[snowystinger]

I was thinking very simple. IE, only allow bold. I'm not too worried about perf, it's a short string for an element that doesn't appear frequently and shouldn't rerender much.

I guess that would be good to include also a span tag for the possibility of adding class to specific parts of the text. Might not be up to Adobe internal guidelines, but useful for third-party.

We should be talking about this later this week.

However, you brought up an important point. Which is that this is useful for non-spectrum users. We intend to make a RAC toast implementation which should alleviate this particular use case.

RAC Toasts have landed in alpha https://react-spectrum.adobe.com/react-aria/Toast.html you handle rendering Toasts yourself so can put whatever you like into it. Do you still need this particular PR?

We've still not landed on a good solution for Spectrum side of things
