I would have preferred to use mono repo and I have no problems  using
it since thats what we
use in meta-clang as wella and it would make it simpler to reuse. but
it can be a pain for other people.

310k, I am not sure what is measured here. But here is the breakdown
of sizes for information

1.5G    .
676M    ./.git
16M     ./lld
51M     ./libcxx
3.5M    ./libclc
31M     ./llgo
32M     ./polly
395M    ./llvm
43M     ./compiler-rt
988K    ./pstl
116K    ./debuginfo-tests
720K    ./libunwind
13M     ./clang-tools-extra
7.3M    ./openmp
6.3M    ./libcxxabi
105M    ./lldb
352K    ./parallel-libs
155M    ./clang

Yes it can however, we know that when next release is cut out from
master then we will be
on a 8.x release.
