If your GitHub or GitLab username has hyphens or dashes, should you keep them in your application's ID or replace them with underscores?

Well, on F-Droid’s Inclusion Policy:

The software should use its own unique Android “Application ID” based on a domain name under the developer’s control.

I’m using my GitHub pages domain, since that is under my control. Since that has a hyphen in it, would my apps still get included if I replace the hyphen with an underscore in their application IDs?
