Nice-name in url = Security Risk??

Hasn’t the solution always been to use a secure password?

Does that mean you do not agree with the content of the linked article?

Here’s an article from March 2014 with an answer from core developer Dion Hulse, confirmed by lead developer Andrew Nacin, along with a few recommendations: https://wptavern.com/why-showing-the-wordpress-username-is-not-a-security-risk

Great!
Consensus on the original link:
1- overkill/invalid.

Takeaways from MacManx’s link:
1- Most security hits aren’t from login
2- Most servers will fail before brute password attack is accomplished
3- Most security risks comes from plugins that weren’t updated

Glad I could help, and thanks for summarizing your takeaways! ??
