I hope you don't take this question the wrong way: why is R7RS large taking so long? Is there a consensus problem or just a lack of resources? If it's the latter, is there any way a random scheme dabbler can help?
Think of it this way: if the committee was more cavalier about this we'd have the familiar situation where we start with a great language and then every update worsens it until we end up with an abominable horror show.

Giving your comments on drafts, issues[1], and draft SRFIs is always welcome. The decisions of the Working Group are more complete when we hear more voices.
