Isn't it what Scheme registry was about? Documenting features provided
by each Scheme *thing* available?

To me, the distinction between packages and libraries is regrettable,
but unavoidable. A library is an abstract thing, a package is a concrete

BLAS is a library, cblas, openblas, and ATLAS are all packages that
implement BLAS.

As far as I understand, languages do not have "package managers", it is
"distributions" that have package managers. (Same abstract/concrete

Documenting all available *libraries* for Scheme seems a huge piece off
work, although it should be possible to get an initial list of libraries
by parsing different package repositories. But I believe that should be
very error-prone.

Documenting all *packages* seems a Sisyphean labour as they change all
the time. However, it would have been nice if it was possible to agree
upon a certain html layout, so that different scheme distributions could
export their package list into, and could fetch
those once a night, and format a single page.
