IMO string.Template is a dead experiment.

My original plan was to get rid of % in favor of str.format(). This
seems to have run into objections from folks who don't want to have to
change their code. They have a point: when the string is not a
literal, it's not possible for 2to3 to automatically convert x%y to a
.format() call. So perhaps we should deprecate % formatting and get
rid of it at some later time.
