Good point! As it is said above, it's all just pure theory. But, let's imagine what would happen:

If somehow a "junior" member of your team seems to produce high-quality code (for "junior" standards) that require zero help from other team members, and always on time, then I guess the team would be fine with the "junior" participating minimally in meeting calls (perhaps even with the camera off... now here I'm assuming 100% remote, something I didn't explicitly said before).
