How about this:

(library-name r6rs-de-facto lists)
(library-name r7rs-large-red list)
(sublibraries ())

(library-name r6rs-de-facto vectors)
(library-name r7rs-large-red vector)
(sublibraries ())

(library-name r6rs-de-facto vectors)
(library-name r7rs-large-tangerine vector)
(sublibraries () (base) (s8) (u8)
               (s16) (u16) (s32) (u32) (s64)
               (u64) (f32) (f64) (c64) (c128))

LGTM.  Let's wait for John and others to comment, though, before making any changes.
