The isolation it does buy us is that gvt/ subdirectory is developed and
maintained on a separate mailing list and separate git repo. I think at
some point there were plans to make it an actual module too.

So while you could quip about Conway's law here, I think it might be
better to keep this as it is.

Zhenyu, Zhi, what do you think?


BR,
Jani.
