Based on the number of patches enthusiastically posted to this list,
and the number that ever get in - I'd say the answer is "very low".

I'm glad it is that way, or Lua would be Python. It doesn't mean your
patch isn't useful, or clever. Personally almost every time I use %b,
I wish it had a way to handle escaping. But Lua simply isn't an
all-features-included language.
