stdlib doesn't need the functionality provided by current string,Template, and
if stdlib comes with batteries included, it is better to ship Alkaline

Support for {{ }} syntax and attribute lookup is a way to provide something
simple from the start, that can be later enhanced by using dependencies, but
without rewriting everything to a new syntax.
