I'd rather leave the single letter specifiers and modifiers to the
standards compliant printf and use something like %{foo} as the specifier
for extensions.
I've re-arranged some of the internals to make this easier to implement,
and stubbed out the parsing of the %{} formats. I'm a little unsure what
sort of errors to throw on extension lookup failure.

What are your feelings on implementing things in such a way that the
compiler could use this same sort of extension plugin to perform type
checking?
