Yep, that’s right. And I guarantee, like would bet my retirement savings on it, that someone today has counted on security through obscurity and not realized their new website was compromised a few seconds after they launched it for the first time ever. “I just registered example.com. No one’s ever even heard of it! I’ll just have to clean it up before announcing it”, not realizing they announced it when they turned the server on.

3 seconds.

I had a similar fun experience when I was generating UUID subdomains and was shocked to see traffic in the logs before ever sharing the URL. I've since switched to a wildcard certificate but regardless, you can't really trust the hostname to be secret because of SNI and all that.

That would’ve been quite the surprise! I was initially shocked enough when @ and www were getting hammered. A fully random hostname would’ve dazzled me for a bit.
