I saw this recently https://chromium.googlesource.com/chromiumos/platform2

" We moved from multiple separate repos in platform/ to a single repo in platform2/ for a number of reasons:

    - Make it easier to work across multiple projects simultaneously
    - Increase code re-use (via common libs) rather than duplicate utility functions multiple items over
    - Share the same build system

"

for "multi"-repo (not sure) what really, fuchsia uses something called jiri, and there is still gsync
