There were some issues raised in the thread on llvm-dev:
"Dealing with out of tree changes and the LLVM	git monorepo"  This migration
has been delayed while discussing these issues.  Discussion on that
thread has died down and it seems like the consensus is to move forward with
the original plan, but we are waiting to get some formal closure on that thread.

The deadline for SVN shutdown remains unchanged.  It's still going to be
around the 2019 LLVM Developers meeting.

It's not a blocking issue and there haven't been any updates lately,
you can follow status on this bug:
