Scheme Request for Implementation 221,

has gone into FINAL status.

Here's the abstract:

This is a set of convenience routines for generators and accumulators
intended to blend in with SRFI 158. The authors recommend that they be
added to the (srfi 158) library provided by users or implementations.
If they are approved by the R7RS-large process, they can also be added
to (r7rs generator).

Here is the commit summary since the most recent draft:

Many thanks to John and Arvydas and to everyone who contributed to the
