+1. I do my library collection layouts like this, and don't feel a need
for the implicit rule, and would rather have it dropped -- IMO, while it
may be a minor convinience when dealing with library collections, it
also affects negatively the complexity of the proposed SRFI and its
implementations; in a way you could argue that it's not a convinience,
but a burden, as there's an additional rule to keep in mind when dealing
with library collections.

FWIW, I'm working on a package management tool for R6RS library
collections, which should eventually handle installation, deinstallation
and dependencies between library collections. It will also give the
library collection maintainer some leeway in how they organize the
directory tree inside the package.
