Can I toggle the permission of default group?

#1

Redash is spreading through my company, and many people will create accounts. The problem is the newly created account is automatically assigned to “default” group, which has full permissions. For now I remove accounts from default group in each time, but I’m planning to change the permission of default group by ./manage.py groups change_permissions command. Is there any possible trouble caused by that?
Our Redash is v 4.0.1.
