This is a great find! I asked that very same question not too long ago:
https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/how-to-make-profile-the-default-tab-without-editing-wp-config/

Even posted an enhancement suggestion in trac where I was led to believe it can’t be done.
https://trac.buddypress.org/ticket/3007

Now I find the reference in the link supplied by @zkwc and, lo and behold, it looks like it CAN be done.

I can’t wait to test this out in my new BuddyBuilder theme framework.
If it works well, I’ll incorporate the idea in so users can select ANY one of the default subnavs as group home.
