We've already agreed that this does not constitute an
argument.  The draft still needs to be updated to state
that modules in the report may only be omitted in
extreme circumstances (I thought I had done this).

R7RS is a revision of both R5RS and R6RS (we've taken text
directly from both).  To say it is closer to one or the other is
irrelevant - it is the seventh revision of the Scheme reports,
and to call it otherwise is confusing.
