That is a good idea. The build area for this would still be in
packaging, use submodule or plain git clone to import this as part of
the build for tight versioning somewhere in the android tree in the main
Then there is the issue of shadow/out of tree build for android. I would

Agree, not enough value in doing so.

I thought as much.
