It is seen as useful in the Scheme community, where it gets reinvented

Most of SRFI-39 strikes me as intuitive rather than bizarre (it's
basically plain-old dynamic scoping just using objects instead of
symbols to "name" the "variables"), but I do find the `converter` part
rather odd.
Does anyone know why that `converter` was added to SRFI 39?
I also can't see how to define something equivalent to `progv` on top of SRFI-39.
