Thanks, good suggestion!

In order to make this overridable from any recipe, may I propose the following
patch instead? It has the advantage of avoiding the Python logic altogether, and
using weak defaults so that it can be easily overridden. One thing to note is
that I couldn't find the "sdk" class that was referenced in the Python
code. Does it exist anymore?

The mentioned patch is what I used, and it worked for me when I also added:

  SSTATE_SCAN_CMD = "true"

to the Go recipe.
