If you find a bug in a web browser, that's no big deal. I've encountered bugs in web browsers all the time.

You figure out how to make a web page that when viewed deletes all the files on the user's hard drive? That's a little different and not something that people discover very often.

Sure, you'll still probably have a long queue of ReDoS bugs, but the only people who think those are security issues are people who enjoy the ego boost if having a cve in their name.
