I didn't know 215 was dead.  A shame.  I thought it was a good idea.

292 seems ok, maybe clumsier than 215 but an improvement over the %
mess inherited from C.

What's the deal with the curly braces in 292?  That's not discussed
at all in the PEP.  I don't see what's wrong with

   print "My name is $name".sub()

(which is similar to what 215 allowed) instead of

   print "My name is ${name}".sub()

I understand that preferences can run either way, but I think PEP 292
should face this question instead of ignoring it.
