It's an extraordinarily simple use case, but it is still quite a
common pattern in C++ defines, ie:

#ifdef _DEBUG
#define FEATUREA
#define FEATUREB
#define FEATUREC
#else
#define FEATUREB
#define FEATUREC
#endif

#ifdef FEATUREB
...
#endif

In D, that would look a lot like:

debug
{
version = FeatureA;
version = FeatureB;
version = FeatureC;
}
else
{
version = FeatureB;
version = FeatureC;
}

version(FeatureB)
{
...
}

So for an actual use case and not an abstract example, yes, the
way suggested is not convoluted at all.
