The only danger is that we developing a useful api and hiding it debugfs.
We may be caught and forced to maintain such even if we do declare it as a
work-in-progress...
I'm not that worried about such just yet, we are a long way from having a
mature enough hw and gfx stack to support a ptrace-like interface for
generic GPU debugging.
