Ack to both points, thanks for explaining.

New patch attached.

It's used to add the installed library's location to the list of library
search paths of macOS binaries (at link time):

  An install name is just a pathname embedded within a dynamic library
  which tells the linker where that library can be found at runtime.
  For example, libfoo.dylib might have an install name of
  /usr/lib/libfoo.dylib. This install name gets copied into the
  application at link time. When the dynamic linker goes looking for
  libfoo.dylib at runtime, it will fetch the install name out of the
  application and know to look for the library in /usr/lib.

So it's a different mechanism, one any install target for projects
wanting to support macOS should account for (so yes, upstream).
