Submodules not cloned

There seems to be a submodule URL error. It seems that this doesn't affect all environments, but I got stuck due to this.

git submodule update --init --recursive

Fix was made in the commit 8fbf508d. I'm not sure at which point and which branch @skinoshi or @hoide or @asuzuki want to merge to make it available to users. So, please tell me your plan and give me an instruction if needed.
