${prefix}/share/libc++/v1 , since usr is a prefix?

I agree; that would better match the layout for my local installs. My ${prefix}/share location currently contains directories named clang, man, opt-viewer, scan-build, and scan-view. None of those have versioned subdirectories, but the v1 is consistent with the placement of libc++ header files under ${prefix}/include/c++.

It looks like rust puts this sort of information in share/cargo - not a real option for us.

Based on this proposal I've created a libc++ PR [1]. I got a lot of
pushback regarding installing modules in a directory parallel to
include. I've changed that directory. The current tentative location is

  <prefix>/usr/share/libc++/v1/

I'm still working on a Clang patch to provide the name of the manifest
file.
