I'm not entirely sure python-smartpm should have been added by default in the
first place. I'd say having it there ought to be the choice of the person
creating the SDK, just as with a lot of other tools one might want in the SDK.
For most people I suspect it's superfluous.

This sounds like a reasonable option to me. The split as it is at the moment
exists mainly for trimming the target; the SDK is perhaps less sensitive to
size constraints.
