Right, as at the same libcxx might not compile with "old" clang due to
fixes here and there. Still, we could implement this coupling using
the version check (and some version-to-version compatibility
contract). This is certainly not possible with lld / lldb /
clang-tools-extras.

Note that the full clone of the prototype monorepo currently is ~500
Mb. And shallow clone (with depth = 0) is approx 100 Mb.
