Our backport tracking machinery parses the changesets in that HG repo. That's the only option for 
tracking, because 8u Shenandoah backports are not tracked in JBS. I suspect it would be fine to keep 
the read-only snapshot of old Mercurial repo, so that backports-monitor can still read it.

FWIW, we did the similar history-losing-squash commit when moving sh/jdk9 -> sh/jdk10 for the 
monorepo migration, and that was not very painful.
