It's a silly point, but my instant impression on reading

    This PEP describes a simpler string substitution feature, also
    known as string interpolation.

is "simpler than *what*?".  Perhaps a better title for the PEP would
just be "simple string interpolation".

Otherwise, I like it.

The only issue I have with putting it in string is that this makes it
a touch harder to bundle up for use with scripts that work with older
Python's (I take it the implementation is pure Python and works or can
be fairly easily be made to work with 2.2?).  But I can live with

try:
    from string import template
except ImportError:
    from string_compat import template
