Comment (by bhubbard):

 I think having it in core would be very useful, as it can prevent
 developers from loading duplicates as @moonomo mentioned.

 Example , say I have a theme and plugin, and they both want to load and
 prefetch twitter bootstrap or fontawesome from bootstrapcdn.com. If the
 both manually print to wp_head, then it would show up twice, having a
 filter would prevent this. This would also make it easier for developers
 to say write a function that disables prefetch for a specific page, etc,
 regardless of what was set to prefetch from another theme or plugin
 developer, assuming they all switch to using this new filter.
