Many systems do this AFAIK.
IIRC, the point is that you can set umask to 007 or 002 and your home
directory with owner you, and group you will remain private or at least
only writable by you.
The umasks 007 or 002 are useful if you have some shared folder where
you have multiple users with write access, say:
drwxrwxr-x root:users /home/share
With umask 002, when files are created in this directory by another user
in the users group, all users in this group can edit that file, no need
to modify permissions.
