IMHO, putting them together does not conflict with the "install-and-activate" idea.

The source of conflict for per-font setting comes from when several upstreams want there fonts to be default (such as Japanese/Chinese font overwriting). If there is a centralized place to set the order, this may encourage them to communicate before chaos happens. Of course, nothing can prevent them from keeping their own rules in the per-font config.
