I did some additional analysis on the output of Nikita's script. The number of curly brace usages is inflated somewhat due to duplicate packages. For example, tecnick.com/tcpdf and tecnickcom/tcpdf both have 74 usages, and are the same project which was renamed. Likewise, johnpbloch/wordpress-core and roots/wordpress each have 182 usages, and they are both mirrors of the WordPress core codebase. Another example is magento/zendframework1 which was forked from zendframework/zendframework1 (almost half the curly brace usages have been removed in the magento fork). 53 out of 89 total packages using the curly brace syntax use it 4 or fewer times. 92% of the usages in are in just 25 unique projects.
